Xorg log file
I sporadically follow xorg's build on this machine, a HP Pavillion with a RS300M AGP [Radeon Mobility 9100IGP] graphics card. I recently upgraded drm, mesa, pixman, xf86-video-ati, xserver and various libs. Now graphics programs that want GL fail to display properly (it looks like there's an off-by 1, or so, in the way images display). Non GL apps work fine.
According to Xorg.0.log the R200 driver is used. I'll add my xorg.0.log as an attachement.
Finally, I know this isn't a great bug report. The good news is that I've built all of xorg with debugging symbols, so can help trace the problem, assuming someone tells me where to look.
