Bug Description
Symptom: xorg crashes on windows creation
How to reproduce: No 100% reproducibility, however intensively using 2D/3D acceleration triggers the bug (e.g. by opening several new windows and/or menus in a Unity desktop environment)
Affected hardware: Intel HD Graphics 4400/5000 etc
Affected software:
- kernel 4.2.0-16-generic #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64
- Ubuntu 15.10 with Unity (because of compiz 2D/3D acceleration)
- any other software using direct rendering (e.g. VLC)
Workaround:
- Disable window animations in Compiz reduces the frequency of the crashes.
Use compizconfig-
[original description below]
I get crashes, when I open a new window in an already started application. It happens irregularely, but I can force the crash if I open several new message windows in thunderbird. But it also happens in other applilcations, for example a new terminal window.
This is the output during the crash in /var/log/Xorg.0.log
