Additional information: SNA is enabled in xf86-video-intel Kernel is 3.0.3 Using libva 0.32.0, but it seems the problem is not related to libva as it even happens for non-accelerated content (e.g. webcam video output in Skype). 0x0770635c: 0x7b003c04: 3DPRIMITIVE: rect list sequential 0x07706360: 0xfffffffc: vertex count 0x07706364: 0x00000018: start vertex 0x07706368: 0x00000001: instance count 0x0770636c: 0x00000000: start instance 0x07706370: 0x00000000: index bias How many vertices? commit 786a770f528a0daee2971494352672cb89f48384 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Aug 25 19:52:13 2011 +0100 sna/video: Flush the video state at the end of the operation Or in the case where a second command is received prior to the batch being flushed, the vertex data is not flushed and leads to the a miscompution of the number of vertices emitted.

Created attachment 50514 [details] i915_error_state When playing back a video, some artefacts of the video begin to appear in the upper left corner of the screen after some seconds, then X.org crashes and sometimes even makes the whole system hang (a ~0.25sec sound loop of the movie keeps playing over and over again) when not switching fast enough to a VT. dmesg reports a GPU hung: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 6614 at 6610, next 6615) i915_error_state content is attached.
