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.

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. :)
Do I need the kernel patch, too?
Yes.

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