you indicated it's fine with KMS, right? (In reply to comment #2) > you indicated it's fine with KMS, right? > yes, KMS is ok. Jesse, this is the bug I just mentioned to you on the car. Can you bisect it? I have returned to our Q4 release image, but this issue still exists with below commits.
xf86_video_intel 2.6.0 release
mesa intel-2008-q4 branch
commit 200fa9165d7078a6f36c5c9d3e0c997c2438bde3 (before and close to 7.3)
kernel drm-intel-2.6.28 branch
commit e1a6fcee467556a7e955fe1f7ccc134dd2f974e7 (2.6.28 + 6 patches)
libdrm 2.4.4 release
xserver 1.6
I think this issue comes out because we use direct rendering for compiz since 2009 Q1. and indirect rendering was utilized before, so that we didn't meet the issue.
Updated testing instructions for this code at http://dri.freedesktop.org/wiki/CompositeSwap. glsync should work better with the new DRI2 features. *** Bug 23707 has been marked as a duplicate of this bug. *** |
