It seems that the depth buffer fails on some pixels. This problem was introduced somewhere between Kernel-3.0.0-rc6-git6 and kernel-3.0.0-rc7. Both xf-86-video-intel and mesa are latest git. Could someone please look into it? I've experienced this issue far earlier than the version stated above (i.e. with 2.39 rc's using mesa and xf86-video-intel from git from that time period). It does not occur constantly in my case, just randomly, and not necessarily from application start (i.e. it sometimes started after it had been running a short period of time). I would have mentioned this earlier if I wasn't having ram issues which make it difficult to have any certainty about problems which occur randomly. --------------000502070802050300010904 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit
