Bug #: 44422 Summary: periodic slowdowns in every 30sec Classification: Unclassified Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: aaalmosss@gmail.com
Rendering slows down to crawl for <1sec every 30 secs. It affects everything: 3d applications, video playback, 2d drawing (e.g. kpatience), probably because of the compositing.
I suspect this is caused by r600g, because my other machine running the same distribution but r300g doesn't have this problem. Current 7.12-dev (git-2cd7e5b) seems to slow down less than 7.11, but the effect remains and it is very noticeable.
