Xorg Log (UXA)

Corruptions appear every now and then, and I found no way to deterministically reproduce the bug. It just happens!

It was reported before in:
https://bugs.freedesktop.org/show_bug.cgi?id=50011
And it was fixed then, but it is occurring again.
Seems to be a regression.

Comment 4 Chris Wilson 2012-07-23 08:23:42 UTC

Mehran, the attached Xorg.log is for UXA, did you mention before that you also see this with SNA?

Comment 5 Mehran Kholdi 2012-07-23 08:47:28 UTC

Yes, The Xorg.log I attached yesterday (https://bugs.freedesktop.org/attachment.cgi?id=64495) was with SNA enabled, so I switched back to UXA and it remained.

I tend to have the issue when I'm in my development environment, which is (mostly) when I run lots of memory-consuming softwares and am Dual Monitor.
Also, when it happens it keeps happening, and when it doesn't, umm... I don't know how to make it happen! :)

And one last note, the corruption may not be "small" in all cases. Artifacts like https://bugs.freedesktop.org/attachment.cgi?id=61844 happen as well.

Comment 6 Chris Wilson 2012-07-23 09:23:46 UTC

Ok, I was convinced that this was a new sighting. However, looks like you may be right and the earlier problem didn't just vanish.

Comment 7 Chris Wilson 2012-10-21 17:54:00 UTC

Are you continuing to encounter this corruption? Have you recognised any pattern? Can you attach a fresh Xorg.log after some fresh corruption?

Comment 8 Mehran Kholdi 2012-10-21 18:28:25 UTC

No, I haven't encountered it for a while. Thus marking it as FIXED.
