[Bug 429307] Re: video corruption when changing windows

[Geir Ove Myhr]

Thank you for a concise bug report with all the basic information
needed. There is some more information we would like for this kind of
bug:

1. Can you reproduce this at will or does it happen only after some suspend-resume cycles?
2. Does it also happen if you suspend from a VT (Ctrl+Alt+F1) with `echo mem > /sys/power/state` (after you switch back with Ctrl+Alt+F7)?
3a. From a VT, run `dmesg >dmesg-before.txt`, `sudo intel_reg_dumper >intelreg-before.txt` (from the package xserver-xorg-video-intel-dbg`), `sudo intel_gpu_dump > intelgpu-before.txt` (from the package intel-gpu-tools).
3b. Suspend with `echo mem > /sys/power/state`, wait a little and then resume.
3c. Immediately after waking up, run `dmesg >dmesg-after.txt`, `sudo intel_reg_dumper >intelreg-after.txt`, `sudo intel_gpu_dump > intelgpu-after.txt`
3d. Attach the *-before.txt and *-after.txt files here.

Btw, I think the missing titlebars is a different issue. I think this is
what happens when the window manager crashes.

** Summary changed:

- video corruption when changing windows
+ [i965GM] video corruption when changing windows after suspend-resume

** Changed in: xserver-xorg-video-intel (Ubuntu)
