xorg-server 1.7.6, ATI Radeon x850 Since the last xorg-server or radeon driver update, opengl windows stopped backgrounding properly. They draw over other windows, and there's other weird graphics problems. Adding Option "AIGLX" "false" to the xorg.conf server layout fixes this but was unnecessary before. Additionally, it looks like some buffer isn't cleared when an opengl window is closed so that it will appear for a second if one opens another opengl window. Reproducible: Always
It looks more as if you were doing things incorrectly before. Such problem with opengl windows seems related to compositing and (till KMS/DRI2) it has always worked that way. Only real fix for the problem is to either stop using compositing or to use KMS driver, as that one uses DRI2, which is unaffected by this problem.
Please attach the output of emerge --info, your xorg.conf and the X server log (most likely /var/log/Xorg.0.log).
Please try what Rafał suggested in comment #1. Thanks
Did you guys just not read the post? I mentioned there was a work around.
(In reply to comment #4) > Did you guys just not read the post? I mentioned there was a work around. Did you not read out answer? Your workaround is a hack, we want you to try a real solution. Thanks
Sorry, thought it was just another hack. radeon.modeset requires ~86 xf86-video-ati-6.13.0 but seems to work okay except it breaks certain graphics effects like blender's menus. They aren't black like they were a couple ati/mesa versions ago, but they're very slow or something.
Then please file bug for those issues, we'll try to work things out. Thanks
