Hello guys,
I have some strange artifacts on my screen. First time I noticed this was on youtube. it shows some strange picture tearing on the left lower corner of the screen. First I thought it was some glitch in youtube app, but later i discovered similar glitch in some flash video. I noticed that it's most visible in Anomaly HD, where allmost entire lower left corner somehow flickers. no other games or apps seem to have this kind of problem, 720p HW accelerated video plays like a charm
Is this problem caused by apps, or is it faulty tegra 2? Can I try another display driver? Anyone else encountered this kind of glitch?
I uploaded video captured on my Galaxy W - it's most visible on Anomaly HD
Try a custom from. If it does not work, you might have a messed up GPU
I am currently using overcome 2.3.1, but i had this issue on stock as well...what's bugging me is the fact that no other app or game I've tried seems to be affected
for example shadowgun, zen pinbal thd, modern combat 3...all those games are working with no problem...might as well wait for official ICS update and see if it helps.
ok another funny thing: after installing latest AOKP ROM this happens when booting (same thing happens in CWM recovery after installing CWM suggested in thread)

here is the original video, seems i somehow messed up inserting the link

EDIT:
i'm starting to thing there's something really wrong with my tab...this iswhat i have after applying motley kernel (no screen shifting on previous kernel)
Could my problem be somehow kernel related?

I have this problem too. I see it in the lower left corner of the screen when scrolling through the video wall in the youtube app. If I turn the tab upside-down in landscape mode the flashing/tearing happens in the lower right corner of the screen. However, the problem does not seem to happen in the portrait mode at all.
I'm on stock unrooted rom.
Can you try flashing cm rom with latest recovery? I'm unable to flash latest build with my current recovery. If I flash recovery recomended in the cm tgread my screen starts to scroll from the bottom to the top. If I try to flash the rom with this new recovery same thing happens when booting...same goes with motley kernel as documented in videos above. Anyone else is having this problem? I can live with some screen tearing but that scrolling pisses me off...it makes newer cwm recovery unusable for me.

It's just as esqauw said...when i turn tablet upside down bug appears on different spot ( right lower corner screenwise, left upper corner tabletwise ). I believe tis has to He somehow related to software, because it appears elsewhere on the screen...might be completely wrong off course. Any oppinions?

I was about to link you my thread on this but I see you found it already. I have not looked into this for a few months.
For me the problem is inconsistent so it is difficult to test. Id think if it were a hardware issue then most if not all apps would be affected. Maybe the way the affected apps are writing to the screen is triggering it. Id also think more people would be reporting the problem.
Different roms don't seem to help which could point to hardware or some low level (lower than rom?) software cause. I watched your videos of the boot screens post kernal changes and I have not had that type of problem yet. But I have not rooted or tried other roms either. This may support the low level software cause.
Your information adds support to a software cause with the artifacts appearing in different parts of the screen when rotated. I think a hardware cause would mean a consistent location on the screen.
I cant find the threads now but Ive seen mention that Samsung's implementation of the screen and Tegra 2 on the 8.9 causes a performance lag in landscape that does not appear in portrait. The 10.1 does not have this problem. Maybe this is related to that. The lack of the artifacts in portrait mode would lend support to this.
I hope you find a fix but Ive resolved myself to living with it. Although, I should probably look at warranty options before it expires.
Good luck
What do the graphics look like on this free graphics benchmark app?

I get 2281 in quadrant. lt runs smooth with no problems or glitching. but it runs in portrait mode which does not appear to have the bug.
Given that bug does not happen in portrait mode I'm leaning toward the problem being the performance lag issue I mentioned above.
Same here

Ok, so I have to clarified couple of things about lag and stuff.
1. I was played GTA 3 v1.3 with all the in-game setups at max and with frame limiter disabled. It has lagged as hell! Then, I switched the game to "Zoom to fill screen" and the game runs very very very smooth but the screen resolution became low. This is applied also to Asphalt 6 and other HD games.
2. The tablet runs smoothly in Portrait Mode. The stock launcher from 3.2 runs perfectly in portrait for me.
3. I tried to overclock up to 1.5 GHz and tried again to play GTA 3 with the option "Stretch to fill screen" and it LAGS! Tried with "Zoom to fill screen", no lag at all but screen resolution problem. Otherwise, is playable
I think all it's related to software. Hardware is quiet good. Maybe if we change the DPI the lag will dissapear, don't know
Jellybean seems to fix it
Well I tried the AOSP 10 beta 8 build and CM10 latest build and they both appear to have fixed the problem. AOSP seems a bit better performance wise so ill be sticking with that for the foreseeable future. I guess it was software after all.
I have the exact same issue with newly bought tab 8.9 on youtube app. and I didn't use alot of other apps but the apps I tried never had issues with the screen. The tab is all stock.
so, what we have concluded here is that it is a software issue or some hardware issue that should be taken care of by the warranty?!
Well it seems that it's software issue,because after flashing CM10 preview, those artifacts dissappeared.

That's great news. But that leads to another question
Do all gtabs 8.9 have the same issue using HC 3.2? So that we can say that we have a software issue only? Or is the issue related to some faulty SoCs that may show these artifacts using stock software?
I just want to make sure that it is a software issue only as I think I can make use of the warranty at the moment if it is a hardware issue
Thanks for sharing the tip

I'm having an odd issue... Anyone with the 9.7 while holding the tab in portrait view on a screen with lots of text or horizontal lines and plenty of scrolling: while scrolling, does anyone else's display seem to scroll sloppy? The right side of mine scrolls faster than the left. Marginally slower, but noticeable. Makes scrolling seem wavy or wobbly or bendy from right to left. If it's just me, I'm going to exchange this one.
I understand about refresh rates n such. I'm going to Bestbuy today to test the floor model.
OK to update: I tested the floor model at a different Bestbuy than the one I purchased mine at and experienced the same "wavy bendy effect" while vertical scrolling in portrait. So, I'm going to assume it's normal and the refresh rate just can't keep up with high resolution and dpi. In case any other S2 owners see this effect.
Have you show this problem to any of you friends or family, can they see your problem, as some people can be more sensitive to screen refresh problems than others, also oled display can have refresh rate problems.

I have. Unfortunately I'm the only one who can see it. Then again I can spot a dead pixel from 10 feet away. :silly:
I had the original Samsung Note 1 phablet and it had an problem with ghosting while scrolling though menu`s ect, the oled pixels take an lot longer to wake up than lcd pixels, so Samsung sent out an firmware update that kept the pixels on at a very low level all the time to increase the refresh rate and fix the problem with the ghosting.
It been an few years since the Note 1, and oled display have advanced since then, but trying to make the oled displays more efficient i hope they have not turned off the pixels completely or low as they can get away with most people cannot see the refresh problem but you can.
I don't know if this is the reason you are having the problem, it could be something else completely.
Have a look in the developer menu in settings, try the use gpu when drawing or whatever it`s called and see if it makes any difference.

I'm thinking they may have turned them back off. The blacks are very black compared to my other devices. Hmm. I have updated to 5.1 to see if that'd resolve it but it didn't. It's not a huge issue, just weird to see but once I get used to it I'll be alright. Hopefully. lol
Motion Blur is what we called it, not ghosting have a look at the link below, it shows motion blur on the S4 see video, I could not see the problem myself (don't have fighter pilot eyes ) , see if it is the same problem you are having or is it something else.

I'm having issue with screen turning pink when using Chrome as browser. It happens only for 10 to 15 seconds. I wonder if that's hardware or adaptive display problem.

Similar. But instead of it being uniform horizontally across the display, it gets "worse" from right to left more than likely because of the resolution and DPI compared to the S4. But same effect.

That I would say is not normal. Is it only Chrome or are there any other apps that exhibit this color change?

The Tab S has the same issue, but it only happens in portrait mode, seems to be ok in landscape. If i flip the tablet 180 in portrait mode it will do it the opposite way, so its not an optical illusion!
It seems like the control chip for the display is suffering some sort of micro lag.
Have you tried the "forced GPU rendering" in the Developer option, I mentioned in post 6.
John.
Nothing solves it, its just the way it is. I gave up bothering about it and forgot about it until this thread . Another reason to stick with 16:10 instead 4:3.
Indeed. Forced GPU rendering changes nothing. That's one of the first things I tried.
Have you tried playing an HEVC H.265 1080p video yet, to see if it stutters like it does on the S1, the S2 is supposed to have hardware decoding, the S1 uses software decoding that kills the battery and stutters.
HEVC H.265 are half the size of normal H.264 video`s for the same quality.
John.
I have a black and white Tab S2 9.7 and both have the same issue. It doesn't look like motion blur, it looks almost like an intentional wavy/wobble animation when scrolling in any app. Which is why I was looking for an option that toggles it. It's very noticeable by anyone who has used it. I pre-ordered it so I didn't get to test it at Bestbuy before hand. I've never seen this scrolling issue on the old Tab S, Nexus 9 or even an IPad Air 2, I've had all three of them. Just when I think I've found a decent android tablet another issue pops up. If there is no fix and this is considered "normal" then I'll be returning them.

I played a heavy HEVC 4096x1720 and it plays the video perfectly on the standard videoplayer, but it stutters when using VLC so I guess the standard videoplayer has a way to hardware-decode this while VLC-player has to use software decoding?
Very nice, hevc hardware decoding is the only thing i am envious of the S2, And 4096x1720 is amazing, unless it`s only really processing the max resolution of the display, and with the stock Samsung player too, does it support AC3 audio though in the stock player.

The name of the file is tos-4096x1720-tiles.mkv, unfortunately the standard player does not support the used audio codec in that container. When I check the file it says 5.1 sound.
VLC does play the audio but as already said the video stutters heavily.

The audio on that hevc video was AC-3 so it look like only the Tab Pro gets AC-3 decoding
And off to the S2 section woosh.

Hey,
I just got my Note 8 in germany and i was experience some random reboot issues with my phone when using it in no special way.
First of all i thought it might have been due to using the pixel 2 launcher but then I found out that its happening everytime i try to play a 1080p60fps video.
I also experienced having troubles with green artefacts when watching some videos on youtube.
I tried watching in safe mode and with sdcard in and out and its still happening.
Is this a common issue with the note 8 or do i possibly have a Note 8 with a hardware problem?
Thanks for help!
edit: when on performance mode its doing a little better. it takes a little bit to reboot but still no way of actually watching the video due to the artefacts
Exchange your device, artifacts and random reboot on different workloads, means there is a malfunction
Hello there, i've noticed some gpu artifacts in games like in the videos below (look at the left side of the screen):

They're pretty random, but it can easy be reproduced while changing volume.
Do any of you face this bug?
Just tried it with PUBG mobile, can not reproduce this..

do you have asphalt 9, if yes can you test it?
Yeah, I have the same issue. But if you start the match in PUBG, there won't be any artefacts. I would guess it is game related, cause the artefact only in the main menu.
it was happened on my xz1 on oreo, but its gone with pie update

Hi, i have the same problem with artifacts, and they also reproduced every time by pressing volume button. I also noticed that when you change the screen resolution in the game to a lower one, the size of the area with artifacts increases, so the problem is probably not in the display itself, it is in the GPU.
It is strange that there are so few reviews about this here, because judging by the Russian-speaking forum 4 PDA - the problem is quite common.
Also, i just find interesting thing , If you enter the developers menu and turn on the "Disable hardware overlay" option, the artifacts disappear ?. discovered just that, in the game oddworld new n tasty.
THANK YOU

Hi guys. Recently i buy a second hand ROG phone 2.
From what you see in the first video Display glitches very bad everywhere, menu, youtube, chrome ect.
Methods i already tried.
1. Roll back to android 9, display Glitches return when i restart the phone, even in boot logo.
2. Return to last official asus firmware but the gliches returned.
3. I recorder the screen with the in build screen recorder and the gliches don't appear, what can that mean?
There is a hardware issue or software?
What suggestions you recommend me?
Thanks in advance
