Just noted that I have maybe a defective screen (or GPU?).
Sometimes when using apps like XDA, browsing or apps with a lot of white background I noticed black lines (1pixel width).
When you holding in portrait mode their appear on the bottom side of he screen, and are horizontal. Always very fast, they appear and then go very fast. Sometimes its only one horizontal line,sometimes two.
When you hold in landscape mode they appear on the whole screen (vertical lines). It happened to me know two times while typing this post.
I'm full stock, not rooted. I have the power plug on and charging, maybe some power oscillation? Will see if happens without charger.

I thought I was going crazy when I noticed this! I legitimately see black lines down the screen for about a second just slightly out of my peripheral, and then they're gone.
Happens on xda and chrome, it's a known problem. Some people say other kernels help get rid of it. I think it's just a software bug.

I also noticed these kind of lines. It happened while watching some videos on YouTube. Also on XDA, portrait mode, on the upper side of the screen. Anyone has a software solution for this? I am just afraid not to get some permanent lines like this.

So... seems like that the problem appears for me only when I'm charging.
Anyone can confirm that the lines appears without charger plugged in?

Yes, the lines appear without charging.

Happens to my Nexus 7 also. They appear very briefly, like for half a second. Usually in the bottom half of the screen (I can't even tell if it appears at the same spot - it appears so briefly, but I do think I have seen it once or twice in the upper half). I have seen it on xda app, Tapatalk app, and Chrome blank page. I think I may have seen it on the home screen also.
On my Tapatalk app I turned the background to dark gray and font to white, but I have still seen it 1-2 times, so it doesn't just happen with white backgrounds.
Don't know if its a software issue and can be fixed with updates or should I get it exchanged? It will be hard to make the store understand what the problem is since it is quite rare, happens to me only a couple of times a day or so (although I have been playing Angry Birds extensively recently to see if it app specific or not, and I have yet to see on Angry Birds - I actually have not seen it anywhere for the last couple of days since I started playing AB).
I only get them in the Tapatalk app. And it doesn't happen often enough to be annoying so I don't really care.
Here here!!
Had them on Tapatalk, dolphin browser and on Plume to name a few. Like others said though, they ain't frequent tto become a PITA but are still noticeable.

I swear these threads are going to appear every week talking about the same problems that have already been discussed many times over.
As said many times before, this is a common issue with tegra 3. The one x line flickering was fixed with an update.
Or you can download a custom kernel with an increased panel clock rate and be happy.
So anybody else have screen raise on the left or is it just me???? just messing.

Saw it on Angry Birds too. So its just not on xda or Tapatalk apps.

A custom kernel does fix it. I had this problem until I flashed the motley kernel and it went away. Then I when I went to the paranoid android ROM I didn't know at the time but it changed my kernel back to stock... I didn't realize it had changed until I noticed the lines again. So far I have used the Trinity kernel and motely's and both have solved the screen tearing problem. If you don't want to flash a custom kernel I'm sure google will fix it in a future update. Thankfully its not a hardware problem.

Really happy that the problem can be fixed with a software update.

Yep, I've seen it happen with the xda app, and it looks like it flickers a line for a second and goes away.
i have this as well, a dark horizontal line appears in a flash of second at random time and place, i thot it is the flicker issue ppl talked about?
but i dont have the whole screen flicker tho i have tried google map zooming or panning with gps on and weak wifi signal and auto brightness off and 15%

I've had my RAZR i a few weeks now and on certain screens, vertical banding is clear from top to bottom when in portrait. It's more noticeable on screens with solid colors. For example, the blue screen when Facebook is loading and the grey screen when My Apps page is loading on Google Play. Its not excessive, but is visibly there.
Is this normal for the screen? Are other people seeing this light banding, or is this just my phone? I don't see the same banding on my old Nexus One.
I'm not seeing this on my RAZRi. Just checked it on both apps you mentioned

Ya dame here thought it was just like the glue on the back of the screens like the on the 910's
Sent from my XT890 using xda app-developers app
Hmm. I think I'm going to take the phone in a get a replacement.
Not just camera app but when viewing certain black colours in image gallery and on internet! Probably about 10 lines equally seperated over the whole screen especially when trying to display mostly black but also with white on the screen. It's really hard to describe. It's actually most noticeable on the camera button in certain exposures on camera.
Any feedback would be welcome as I have only a day to take back!

On which Rom are you? I saw this too and upgraded my Rom to latest ARHD and it's gone I think, or at least I can not go d the right angle anymore.
If I see it again I will report back.

Hey every now and then when using my one with the stock keyboard i notice lines flicker at the bottom of the screen, but when i look at the bottom of the screen i never see them. I thought i had bad eyes so forgot about it. Then my friend bought a htc one as well and within 2 days said he was noticing the same thing while using his keyboard. i am on ARHD 8.0 but have had this problem from day 1 even on stock rom. has anybody else noticed the strange lines.
Thought I was the only one lol

John.
do we have any solution for the screen flickering of HTC one M8???? anybody have some idea.
I flashed fxp250 and have experienced blue screen. I found that it happened randomly. No special apps trigger blue screen, nor high cpu load. I hv just experienced 2 blue screens...
How many times do you experience blue screen per day?
And what triggered it?

Many time per day isn't true for me. But maybe 3 times per month and I have CM 11 Android 4.4 every build. Blue screen I had only in big strain.
