black lines appears in split second

[kwill]

I am experiencing this issue also. I can't remember exactly when it started, but I bought my tablet on Aug 2nd and updated to JB within a day or two of its release. I also reported the issue so they can get an idea of the scope of the problem. Here is what I wrote:

I am experiencing the issue with black lines flickering across the screen since the Jelly Bean update. It is especially noticeable on a white background in apps such as Evernote, but happens across many apps. I have been told that others are reporting this issue as well. I am reporting it so that you may know how broad an issue is and respond accordingly.

Hello all new to this forum. Was searching around and saw this issue with black lines.....i am having the same problem but with white lines flickering. I recorded it if anyone wants to check it out. It happens like others when browsing online.

They asked me to data wipe, which I did, and it did not solve the problem. This is the response I got:

If the problems still remain after wipe data,I suggest you to RMA it to have it repaired.

I hesitate to do this since it might be a software issue, but obviously I don't want to see it get worse or wait until the warranty expires. It does seem to be getting worse--not more frequent but the lines now appear to be running the length of the tablet and then angling down at 90 degrees to run the remaining width.

I have been able to reproduce this using the stock email app, and the Black Hole live wallpaper (that one causes the lines almost immediately). I have also been able to reproduce this in Evernote and the Dolphin browser. So, other than the Black Hole it seems to happen mostly on apps where the screen is mostly white.

I was noticing this random lines on my tablet and tried the Black Hole wallpaper and I was able to replicate it. Most be some issue with the graphics HW or SW

I contacted a different person at Asus (the one that works with customers who leave negative feedback on Newegg.com) and after a brief exchange, he agreed that I really should RMA the tablet. So, I'm going to give them a chance to fix it.

I had the exact same flickering line problem since the JB update. My T700 is only two weeks old, so it really annoyed me.
Like a user here on the forum said, the problem is reproducable with the Black Hole Live Wallpaper. Another one said that a downgrade back to ICS solved the problem for him, so I downgraded back to ICS and voilą, no flickering lines so far (at least not caused by the Black Hole Wallpaper, I stared like a maniac for 3 minutes on my tablet and no flickering lines appeared ). Maybe some of you might find this information useful, so there you go
I think I am observing the forums from now on and wait for a fix. Until then, I won't go back to JB.

I just installed Words With Friends and I'm seeing a black flicker, quite often, down the left side of the play area. This is a vertical line from top to bottom....but it may be a bug in the app or just the way it refreshes.

Yeah. So it has to be a software issue. Well, I'm taking one for the team and sending mine back (they were kind enough to provide a pre-paid Fedex RMA return label at least). With it, hopefully they can identify the software issue and release a fix for everyone. It's a shame for something like this to blemish an otherwise outstanding device.

I confirmed earlier in this thread that the problem isn't present in ICS after a downgrade. So it is software... They just need to figure out what's wrong and I'm thinking graphics driver, but I could be wrong...
