Bug ID: 87625 Summary: Radeon 7950 hangs for a bit when switching video to fullscreen mode in mplayer2 Product: Mesa Version: 10.3 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: luke-jr+freedesktopbugs@utopios.org
When I fullscreen a video in mplayer2 (gl3 vo driver), my display freezes - usually for a number of seconds - after which the fullscreen completes successfully and continues playing.
Sometimes the hang is very brief or even unnoticable (I think if I had recently played a video fullscreen - which may make troubleshooting harder).
During the hang, CPU appears to be idle, I *think* I/O wait is high (but nothing showed in iotop), and perf top didn't notice anything busy.
This does not affect my 5850 card, only the 7950.
