             Bug #: 53632
           Summary: Radmon rendering corruptions
    Classification: Unclassified
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: v10lator@myway.de


I get random rendering corruptions in Minecraft with a CAYMAN GPU (radeon HD
6950).
It seems like the wrong textures are selected, see:
Good: http://img713.imageshack.us/img713/492/mcgood.png
Bad: http://img96.imageshack.us/img96/6417/mcbad.png

Also water seems to (randomly) choose the wrong texture in it's animation,
resulting in flashing water. Also the game screen flashes blue sometimes.

There are no error logs at all and this seems to be triggered by Michel Dänzers
patches to fix bug #45018 (see comment #119 there) as it wasn't there before.
Please note that this has nothing to do with GLAMOR acceleration (not used when
the corruptions occur).

Can you bisect which commit exactly triggered it?

Do you have Jerome's kernel fix referenced in that report?

Sorry, done.

> Can you bisect which commit exactly triggered it?
I'm not that good at bisecting (never did it) but I could try to remove your
patches one by one. Would that help, too?

> Do you have Jerome's kernel fix referenced in that report?
No. It's a 3.5 kernel without (DRI related) patches. Do I need the kernel
patch, too?

Yes, that would be the poor man's way to isolate the commit. But you should
really learn to bisect. :)

Yes.

The patch seems to fix my issue. Sorry for the trouble.
