Summary: [r300g] Fullscreen OpenGL game now has occasional flicker (bisected) Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: rankincj@googlemail.com

Playing World of Warcraft fullscreen with my RV350, and the screen is now occasionally turning pitch black for a fraction of a second. No other side-effects noticed, but the "flicker" is annoying.

The pitch black screen isn't completely blank - it looks like the minimap is being rendered (briefly!) in the bottom LH corner of the screen.

My limited git-fu has narrowed the problem down to this commit:

16887d042a917fa4773e4d853f50051b54e9948c is the first bad commit commit 16887d042a917fa4773e4d853f50051b54e9948c Author: Kristian Høgsberg krh@bitplanet.net Date: Fri Aug 27 12:40:11 2010 -0400

glx: Drop broken drawable garbage collection

Doesn't work for pixmaps, was looking up the GLX XID and was never thread safe. Instead, just destroy the client side structures when the drawable is no long current for a context.
