Description Balló György 2010-12-17 15:46:14 UTC 
With the current xf86-video-intel driver (2.13.902), OpenGL-based applications are not displayed correctly, and sometimes they crash X. I use an Intel 845G graphics card. When I revert the following patch, it solves the problem:
"Disable BLT for i830 and 845G"

Comment 1 Chris Wilson 2010-12-20 03:00:03 UTC 
With information about the crash, I can't fix those bugs since they are bugs in X. However, the offset graphics are a regression, so reverting for release.
