           Summary: ATI Radeon 6950 (Cayman): r600g texture / pixmap
                    corruption
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon

Xorg.0.log

I don't know where this should go (drm, mesa?), but after a while, I notice
corruption of textures / pixmaps. It can be reproduced quite easily by opening
a few applications, or starting another X session. In particular, I could
determine the following:
 - Corrupted areas resemble parts of the previous visible login screen
 - Icons, fonts and widgets like vertical gtk progressbars get corrupted, but
only their lower half
 - Window (emerald) decoration seem to get corrupted completely.
 - It's not related to color tiling.
 - Pageflipping is enabled.
 - Restarting a corrupted application fixes it temporarily, while minimizing
etc. doesn't. Restarting compiz doesn't fix it either.

I believe this is specific to cayman, as the issue does not occur on a thinkpad
t400 with ATI Mobility Radeon HD 3400 and similar configuration.

Software configuration:
 - linux-3.0.0-rc1 with latest fixes from drm-2.6 git applied, up to
2a9e5862a38f7195931bd51788dc9ce68b28120c.

Screenshot of corrupted xfce panel plugins.

Here, parts of a previous screen (gdm login screen) shine through the lower
half of the plugin widgets (gtk progress bar). I guess the gdm login screen was
not active on any console at this time, so these are just remnants.

Reloading the panel fixes it.

Screenshot of corrupted firefox toolbar

Corruption can get quite nasty after a while. The ugly pink background once was
a somewhat nicer image from some firefox persona theme. There are more of those
corrupted icons too for those who got a taste of them ;-)

Small inexactness on my part. I pulled from drm-radeon-testing branch, not
master, which should already have the blitting support. I do not have all
commits from the last 5 days though, the last one was "fix oops in ttm reserve
when pageflipping (v2)".

I might give 3.0.0-rc2 a try together with drm-radeon-fixes, but after glancing
over the changelog I wonder if this is really going to help...

It did not help, though it delayed the problems.

However, I've upgraded to 3.0-rc2 and this solved all my problems. I'm not sure
about this, but I think the problem was me pulling from drm-radeon-testing
instead of only cherry-picking the latest commits. If this is really the case,
I apologize for wasting your time.

> /me hasn't run compiz on cayman yet too much.

It works really great! Thanks for providing a better experience with the
open-source drivers.

Unfortunately, I have to reopen this bug, as the corruption returned as soon as
I tried to start a 3d game (naev: http://code.google.com/p/naev/).

- some fonts in the menu were corrupted and unreadable
- exiting back to the desktop shows the same corruption mentioned before
(window decorations, icons)

However, it's a bit better now, as it did not happen during normal desktop
usage (till now).

I have similar experience on HD6990, usually I have horrible pixmap corruptions
with random memory content. PM also doesn't work, and I have turned it off.
Nexuiz works fine, but after using okular things go quite bad.

I thought it was time for an update, but unfortunately this is still not fixed
in 3.1-rc9. Isn't there anything that can be done about this? All in all, the
driver works mostly fine, but the corruptions are very annoying and disturbing.

I've been having progressing icon, font and widget corruption in KDE4 and
firefox for a over year already. It is easy to trigger this if I scroll quickly
through a PDF file in okular; heavy texture use or memory shortage trigger it
reliably too. The symptoms are essentially the same as Harald described,
although on a radeon 9600xt, opensuse 11.4, linux 3.1-rc5, Mesa 7.11.

That's probably a different issue from this one (which really seems Cayman
specific) then. If you can still reproduce the problem with radeon.agpmode=-1,
please file your own bug if there isn't one for your card (generation) yet.

This has been fixed with attachment 52762 from bug 40221.
It does not occur anymore in kernel-3.2-rc1.

I'm therefore happily closing this bug.

Thanks.
