Dump from /sys/class/drm/card1/error

The system hangs for a few seconds, then dmesg spews this:

[  197.405192] [drm] GPU crash dump saved to /sys/class/drm/card1/error
[  197.405193] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[  197.405194] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[  197.405195] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[  197.405196] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[  203.441104] [drm] stuck on render ring

And the system continues.

Untill reboot random glitches (mostly white bars and blacked out textboxes) appear

Also, around the time this started happening, bumblebee started rendering black windows when using Primus as a bridge. VirtualGL looks normal.

Primus can be fixed by setting environment variable PRIMUS_UPLOAD=1

Acceleration method is SNA
changing to UXA seems to make it worse

Comment 5 Robert de Jager 2014-03-19 09:39:46 UTC 
The artifacts and glitches appear even before the render ring error. It seems to be getting worse
Comment 6 Kenneth Graunke 2014-04-13 17:27:50 UTC 
Hi Robert,

Can you try running KWin with EGL and see if that makes your artifacts and GPU hangs go away?

KWIN_OPENGL_INTERFACE=egl kwin --replace &

Thanks.
Comment 7 Robert de Jager 2014-04-14 15:54:46 UTC 
I have used it for a couple of hours with the KWIN_OPENGL_INTERFACE=egl export, and the artifacts seem to have gone away.
Comment 8 Robert de Jager 2014-04-14 15:55:07 UTC 
Hangs also
