Nothing appears in X.org log, but there is this in dmesg: [ 6513.878111] [drm] stuck on render ring [ 6513.878120] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 6513.878123] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 6513.878124] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 6513.878126] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 6513.878128] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. Then the log get spammed with the first of those lines. I think this started to happen like a month ago (either from mesa, intel or kernel update), together with random font rendering corruption (where random set of letters are replaced with black boxes). I’m running an up-to-date arch linux install, on a Core i7-4702HQ. So I think I may be affected too. However, I don’t know how I could help you in any way, I’m new to bugreporting.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
