Description Wei Wang 2006-11-16 22:16:39 UTC 
OS: ubuntu-edgy (32bits)
chipset: i965 (64bits)

Configure xorg.conf to enable AIGLX and Xorg.0.log really tells AIGLX got 
enabled. GNOME starts correctly. And In GNOME, after starting beryl-manager, 
rotating the cube finally make some of the facets cube become white (see the 
attachment) and blink(sometimes).

beryl-manager complains out these lines:

==================================
LibGL warning: 3D driver claims to not support visual 0x5a
XGL absent, checking for NVIDIA
Nvidia Absent, assuming AIGLX
LibGL warning: 3D driver claims to not support visual 0x5a
beryl: No stencil buffer. Clipping of transformed windows is not going
to be correct when screen is transformed.
Initiating splash
berly: water: GL_ARB_fragment_program is missing.

Comment 2 Michel Dänzer 2006-11-22 10:20:19 UTC 
GL_ARB_fragment_program missing is expected with xserver 1.1 and only causes the
water plugin to be disabled. The 965 rendering issues with compiz/beryl/... have
been reported elsewhere I think.
Comment 3 Eric Anholt 2006-11-29 15:29:46 UTC 
You should try with DefaultDepth 24bpp in the Screen section of your xorg.conf
to see if having a stencil buffer fixes the rendering, since the log of the app
says that the app will misrender if no stencil buffer is present.  Also, if
you're using the internal QA branches, those hadn't been updated for Mesa fixes
in a while.

The bug priority was upgraded (P2->high) with the bugzilla configuration change.
I'm Changing the priority back to the normal one.
Sorry for the spam.
Comment 5 Eric Anholt 2007-08-09 13:38:23 UTC 
Feedback timeout.  The program explained that what sounded like the reported failure would happen before it happened, so it's a program bug.

Mass version move, cvs -> git
