[Q] Weird Web Artifacts in CM10.1 - Nook HD, HD+ Q&A, Help & Troubleshooting

I've been running stable CM10.1.3 on a couple of HD+ tablets. I have noticed a weird video glitch in the web browser on several web sites. It most definitely has to do with pages that have pictures (or some sort of image) on them. What happens is the picture gets kind of magnified but not exactly, it is more like a banded blur (about 1 inch wide) which runs the length of the screen. This band always has a part of an image in it which looks like it is being magnified somehow.
This is annoying and makes the site pretty much unusable. Has anyone else experienced anything similar to this?
I tried using Dolphin instead and get random program closures with it. So the stock browser actually seems to work better.

Well, I've upgraded to 10.2 nightlies and still see the same issues.
One thing that might be coming into play is that I have changed my screen dpi to 320. Does anyone else see this?
Also I do have flash installed, but don't think this is flash related.

[Q] Anyone know why or how to fix:

I have a Samsung captivate, and I just finished the upgrade to the new froyo firmware. But i'm having a problem with images i get from websites on the phone. If i download the image, or set it as wallpaper it looks as though i tried to make a thumbnail a wallpaper -___-. It never did this before the updates. I haven't tried using the camera's pics. I know the images are of high quality cause they show fine on the website. The resolution is pretty good as well, just all pixelated after download. This is bugging the hell out of me, makes my phone seem outdated for such a good display. thanks in advance!
Dolphin browser hd. Firefox mobile.
I noticed the same thing. I think its caused by the browser, compressing the photo or something. I eventually caved and downloaded with my computer then used dropbox or USB to put it on my phone.
I didn't try other phone browsers though. You could try Dolphin or Miren browsers in the market and see if they save the picture in full quality.

That's something I've been *****ing about since the very first 2.2 leaks last year, actually. I originally thought it was a bug in the JI6 2.2 leak, but it turns out to be a "retarded-by-design" thing built into 2.2, as it also has the same behavior in the official i9000 2.2.1 and the official ATT kb1 2.2.
I have no idea what exactly is causing it, but for some reason you can't download images at their regular resolution using the stock browser anymore in 2.2. Some smaller images will download fine, others (usually images that are really big - 3000x2000 and whatnot) will automatically be resized and heavily compressed. You can verify this by downloading a big picture, then opening it in the gallery and noticing the drastic drop in quality.
It's only the stock browser, though. You can still download images in their full resolution with a 3rd party browser; it's just irritating to have to do that as a workaround when everything else in the stock browser works fine.
I had no idea that the stock browser did this. You would think it would at least give you the option to decide if you want to compress downloads or not. I personally use dolphin browser hd and would never bother using the stock browser for anything. Other issues I've had with the stock browser include not being able to switch my user agent (so that I'm not forced to view the mobile version of a page). And not being allow to download something just because I don't have an app that can open the file. In short, it's a pretty restricting browser imo.
There are several browsers available from the market. Dolphin HD is a good one, Opera is pretty good too.

[Q] Nook Color Display Color Depth only 65K colors?

Is the nook color limited to 65K colors? This seems to be an issue for some android phones, and I'm wondering if the NC has the same issue. I certainly notice it on mine whether running stock, CM7 or phiremod.
To test for yourself, load this image:
http://marsrovers.jpl.nasa.gov/gallery/press/spirit/20050610a/sunset_a489_gamma_2sub_800.jpg
You'll likely notice banding in the areas where the sunlight fades. Is mine defective, or are they all like this?
My old eris, running CM7 has a similar issue, but it's better at dithering the image than the nook (more likely a result of a smaller screen).
Some discussions point to the default 3d gallery limiting to 16-bit color for performance, and other discussions say Gingerbread is supposed to switch between 32 and 16 bit color on the fly for OpenGL and standard 2D rendering.
I did search the forums, and found the following threads:
http://forum.xda-developers.com/showthread.php?p=14665031
http://forum.xda-developers.com/showthread.php?t=1126542
So it looks like others are noticing the issue. Are there any known workarounds, or are we stuck with this?
Two things:
1. The overclock kernel is 16bit on purpose to help gaming performance. If you overclock you are stuck at 16bits period.
2. In stock Froyo/Stock CM7 most programs still just show things in 16bit (like the default Gallery program). Here is an app that does 24bit for pictures:
https://market.android.com/details?id=com.alensw.PicFolder&hl=en
For videos there is no "solution" except to accept it.
Thanks for the response.
I wasn't running the overclock kernel, just the standard one that ships with CM7 Nightly. Regardless, the same issue was present running stock 1.2.
I had tried QuickPic with the same results - maybe there's still banding in the image under 24 bit and that's what I'm seeing?
It's understandable about switching to 16 when doing 3D for performance, it's just a shame such a beautiful display is limited for 2D image viewing.
I looked at that picture and didn't really see what you were taking about banding. Then I tried to download it to view it with QuickPic. I was using Opera Mobile and I couldn't figure out how to save the file so I tried FireFox and it looked awful. I managed to save with Opera mini,which also looked okay. QuickPic looked horrible, with lots of banding. PerfectViewer looked good.
I'm using FroYo on SD. I tried the OC kernel but went back because I wasn't really using it and I wanted to see if the color depth mattered. It seems like its hard to tell what's doing what. Is QuickPic really 24 bit?

My Screen Flickers While Browsing internet

The screen flickers when there is any kind of light background on any video I play on the internet via wifi. Auto screen brightness is turned off both within the browser and frm the main display setting as well.
Any possible solution to this OR you are having similar issues ?
PS: This happens only on internet. Rest screen is perfect in all activity.
Yeah I know what you are talking. I noticed that same. But believe me... there are more annoying problems out there with that Huge Crap of ours.

Never noticed such, can you give an example website?
It generally happens on any video i play via net, but more noticable on lighter backgrounds. A perfect example would the below video:

People plz post if you are having similar flickering lines.

Bought my note a couple of days back and after reading Galaxy Note Screen Issues!!! thread I spend few hours trying to find any bugs.
Here are my findings:
1. Slight saturation of gray color on upper right of the screen during screen test
2. Screen flickers while browsing internet with stock browser
3. Halo in calc application
3. Patchy plain black image if set as lock screen wallpaper
I think these screen related problems are because of the software bug not hardware (except few cases with dead pixels). Because------
I set brightness to 1% using Elixir and used Opera mini and mobile, Dolphin HD and Mini, UC Browser but screen did not flicker. Even while reading books with adobe reader screen does not flicker. Halo in calc app is the design of the app.
But I am not sure about gray screen issue.
So to be SAFE, tomorrow I am gonna go to Samsung SC and tell em that if these problems persist after forthcoming updates (2.3.7 or ICS) I would demand refund or replacement
PS
We got the latest and greatest mobile available in the market. Its a beast of a phone!! So stop complaining
Sorry for my English its not my native language.
Its been proven that every Note differs. There are ppl which do not have hues or banding in calc app. It shlould be pure blue to black gradient, without any color hues, red or green. It should go out to black quite smoothly, not through gray.

Hue/banding in my calc app looks like 'black-gray-blue rainbow' does it mean my graphics chip is faulty ?

Yes I can see flickering and its quite random, but nothing on the youtube app though just when viewing it in the browser.

OK thx for confirming. BTW, You know any browser i can download that supports Hardware acceleration.
And ppl plz dont start taking abt random screen issues(There is a dedicated thread here for that), be on topic and post your views if there is any kind of flickering/banding while using internet.
Do you get the same flickering using the youtube app?
Yep, I get the flickering when watching flash videos. I've read that it's not just a Note problem, other devices have the same issue. I also belive it's software, not hardware related.
Don't know how to cure it though!
Same here.. flickering in flash videos - top half of the video.

Played this video in Stock Browser. Played via flash player , no problem found. no weird lines or flickering.
I get a brightness flicker while touching the screen during browsing. So far no other screen issues from my subjective experience.
I don't understand why not everyone has that problem. If so, maybe it is really hw related. And that would be bad.. I can't imagine that t-mobile will change the unit But there is still a chance that it can be sw problem, because it makes no sense that other videos are playing ok.
btw: i can also see flickering on that youtube video

[Q] Video quality issues with Netflix and movie players?

Got the Nook HD+ rooted and installed the Play Store
After that I installed a file explorer and Netflix.
It was on playing Netflix that I noticed a big problem, the videos are distorted and pixelated massively. Having done some small web design projects I know that one issue with the retina displays on the newer Ipads etc is the DPI is increased and so normal pictures and videos tend to look washed out a bit. Is that an issue with the HD+?
If not that, could it also be that Netflix itself is thinking I am reaching them from a smaller screen device and streaming the smaller file/screen size which the Nook is expanding to fill the screen making it get pixelated (as happens when you zoom into a video)?
Regardless, I looked in other threads for this issue as I do not believe I am the only person to ever experience this - did not find anything. One last test, I logged into my own home file server and tried to play a movie in one of the folders. Sure enough, it looks fine on the TV and computer monitor but looks a little grainy by comparison - so I have to believe part of this is a DPI issue? Is there a suggestion to resolve this?
Would installing the "real" Netflix from the HD+ market solve this for at least Netflix? (I am going to assume that logging into the B&N site and installing an app that way does not endanger my root or access to GApps/Playstore?) Is there an easy way to get to the B&N app market from the modified dashboard (not CM10) or should I stay away from that if it makes the HD+ more apt to update/modify my current settings?
That is a lot of questions to solve a single problem so is there an existing solution I am overlooking? Or is this just the price of having the greater resolution screen?
That distortion and pixelating happens on all my devices with Netflix. It goes away after a minute or so. It is like the buffer has to fill up before it gets clear.
And I don't think it matters where you get the app, I think they are the same. And getting something from the B&N store has no effect on root or Play Store or vice versa. You are no more likely to get updated. You are already automatically logged in. That happened when you registered your device.

[Q] Terrible Firefox performance - any ideas?

Firefox's graphical performance on this tablet is bizarrely poor. Scrolling is like a slideshow on any vaguely complex/graphical page. This is the case both with Firefox, and its latest Nightly build. Has anybody found any solution or filed a bug for this? The high resolution screen may play a part in this, but performance is far worse than the Nexus 10, which has the same resolution display and far slower hardware.

Contact the firefox devs and tell them. They should be the people fixing it, Quote the stock browser and chrome being much faster.
Firefox beta runs fine on mine. For example, CNN or Yahoo News scrolls smooth to me.

Yeah, this browser is supposed to be one of the best, but on the TF701 it is really buggy and laggy... hopefully they will fix the issue. Right now I'm using stock and Opera, occasionally Chrome
