Since I have updated to Ubuntu 13.04, every time when I plug in a second monitor compiz crashes.

Sometimes, when my computer has a high CPU Value, compiz also crashes. When Compiz crashes, the launcher-bar and the menu and frames of the windows are missing and I have to restart my computer.

I think the problem could be the graphic card: I have a HP Probook 4720s. When I run lspci, the following line shows my grapic card:

`01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV710/M92 [Mobility Radeon HD 4350/4550]`

If you need more information, tell me how to gather the needed information and i will post it.

Thanks for your help,

I have the same problem, don't reboot, just start "compiz config manager" and toggle checkbox on "Window decoration". It is still annoying, but will do the job for now.

Thanks for that workaround. – Reflic Jun 13 '13 at 15:59
