            Bug ID: 85526
           Summary: Screen corruptions in OpenGL reliant applications
           Product: Mesa
           Version: unspecified
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: hamish@icculus.org

Image corruptions in Chromium, Blood II: The Chosen through WINE, and Quake III
Arena

I have been having a very confusing problem with the version of Mesa packaged
with Arch Linux. I am using a Diamond Radeon HD 4670 with R600g.

Yesterday I updated the various Mesa packages from 10.3.1-1 to 10.3.2-1 and
upon doing so I started to encounter screen corruptions in all of the games I
tested as well as the browser Chromium.

Reverting to the previous version packaged by Arch Linux fixes the issue:
cd /var/cache/pacman/pkg/
pacman -U mesa-10.3.1-1-i686.pkg.tar.xz mesa-dri-10.3.1-1-i686.pkg.tar.xz
mesa-libgl-10.3.1-1-i686.pkg.tar.xz mesa-vdpau-10.3.1-1-i686.pkg.tar.xz

While the bug itself is of course distressing, the main thing that is confusing
me is that I am even having trouble finding mention of Mesa 10.3.2 release as
the website does not mention it and I can not even find an entry for Mesa 10.3
in the Version field of this very submission form.

Games seem to run without any stated errors in spite of the corruptions,
something which is making it difficult for me to find any additional
information. I have attached screenshots showing off some of the problems I am
talking about.

I apologize if this report is too vague or if I am missing something with
regards to the Mesa version information, but this is the best I can figure out
for the moment. Any suggestions as to deriving more useful information would of
course be appreciated.

Can you bisect mesa to indentify the problematic commit between 10.3.1 and
10.3.2?  there are only a few changes between the two versions:

So it looks like "r600g,radeonsi: Always use GTT again" is the culprit. Sorry
for doing it is as two posts; this my first time bisecting and I did not
realize at first I needed to do one more step.

I don't have bad rendering during normal renders like you guys, but when
mousing over the bookmarks bar in chromium the overlayed boxes are usually
corrupt for me now. R9 270X.

Sometime the website takes a bit of time to update as I don't the have access
to it atm. Similar story for bugzilla. I'll take a look into getting those
resolved.

Announcements can bee seen in the mesa-announce ML archive [1], which includes
mesa 10.3.2. If you're interest in testing mesa just before it's released, keep
an eye open for "New stable branch X candidate" style messages on the
mesa-stable ML [2]

Pardon for the off topic gents.

Does running the affected apps with the environment variable RADEON_THREAD=0
work around the problem?

And that's caused by the same Git commit? I.e. if you revert that commit, the
problem goes away?

Running "RADEON_THREAD=0 quake3" from the terminal still produces image
corruptions for me with 10.3.2.

I've had the same issue in chromium with a 280x. (well I haven't tried on
bookmarks, but on any other overlay)
I found a way to get around it, just move the cursor away, and move it back on,
then your overlay should be fine.
I *felt* that this issue came from chromium's new ui library, but truly I never
tested it so maybe it came from gallium3d.
I'll subscribe to this and maybe I'll try building mesa without that commit
later this week.

This may be the same or at least related to bug 84627, which seems caused by
something subtle in the kernel.

Booting into the exact same kernel for 64-bit does indeed make the problems go
away for me. Gentleman, I think we have a suspect...
