gpu crash dump

When I opened new tab in chromium the whole window disapeared. Other
applications (firefox, urxvt, thunderbird) seems unaffected.
In dmesg I found this message:

[3124886.293582] [drm] stuck on render ring
[3124886.294091] [drm] GPU HANG: ecode 0:0x00000000, in chromium [3015],
reason: Ring hung, action: reset
[3124886.294092] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[3124886.294093] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[3124886.294093] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[3124886.294094] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
