mir crashes after screen lock

[Michal Grňo]

I'm using experimental unity-system-compositor in Ubuntu 13.04.
It seems to me that Mir crashes after every screen lock. Sometimes it shows incorrect letters (upside-down "A" instead of "u") or just begins flashing with various colours.
I've got "Gallium 0.4 on AMD CEDAR" driver, 32bit system, unity-system-compositor version is "0.0.1+13.10.20131015-0ubuntu1".

Attached the "flash-crash" screenshot.

After reinstalling unity-system-compositor, I'm unable to reproduce this bug. My laptop force logouts on suspend but works great after screen-lock... (Only once, the windows remained behind the "type your password" dialog. So the bug report it's invalid, isn't it?

[Michal Grňo (michal-grno)]

Ok, reproduced again. The system logged out automatically (why?) and after login, nautilus freezed for a while and then, unity was showing empty char instead of lowercase "k" in some windows.

[Daniel van Vugt (vanvugt)]

Thanks for all that. The logs seem to be from when the system was working though, so don't show a "crash".

Could you please reproduce the problem again and then look in /var/crash for relevant crash info? If it's there then run:
    ubuntu-bug /var/crash/SOMETHING.crash

Also, immediately after reproducing the problem please take a copy of:
    /var/log/Xorg.*.log
and attach it here.
