I originally posted this elsewhere but have yet to receive a reply, so I'm going to do a direct copy/paste, hence there being another post compressed into this one at the bottom.
I'm not sure whether this is down to a driver
update, a Windows update or something else. It's been happening for about a week, and happens after a few hours on both 13.4 WHQL & 13.5 beta2 (yes -- I've tried uninstalling drivers
and reinstalling, etc). Curiously, reinstalling the drivers does appear to delay the issue's reappearance.
My card is an XFX 7950.
Here's is what I'm talking about
It happens irrespective of whether I'm overclocked, at stock clocks or underclocked. My temperature (idle) is about 50C.
If I disconnect the first monitor, the second monitor inherits the corruption immediately, and vice-versa.
This happens on both Chrome and a clean Firefox installation.
This only appears to happen when watching YouTube videos. Heavy gaming does not produce similar problems.
Closing the window with YouTube open usually
solves the issue, however not always.
The only potentially relevant software I've installed in the last week is an Adobe Flash Player update, however I think this was after the problem first arose.
The only Windows update I've installed in the past week was a security update (KB2840149
What on earth is at fault here? This is such a peculiar problem.
Was just doing some more testing with Nightly (Firefox) and it gave me a BSOD.
My current assumption is that this is a flash player/video card driver conflict, so I'm trying to disable flash hardware acceleration. The option under control panel -> screen resolution -> advanced -> troubleshoot is greyed out.
Edit: Completely uninstalled flash player, still happening. Going to try uninstalling the video card drivers and then reinstalling them bar the bit about video decoding/hardware acceleration/whatever AMD calls it.
Edit: Currently have 13.4 display driver + catalyst installed but nothing else from the driver options. No flash player. Currently no problems, will stay like this for a few hours and see how it goes.
Edit: Still managed to corrupt. Going to try the above again but for 13.1 where it didn't see any issues.
Edit: Uninstalled using Atiman, installed 13.1, still happens. What the deuce? Anyone, help?
Edit: Tried a system restore to three days ago, no dice.
