Public bug reported: When I have high I/O and CPU load - pls also see following top output -, for example a complicated MySQL query, compiz crashes, mostly when switching between workspaces, but sometimes also under other conditions. The window decorations are lost, strange foreground/background bahaviour of the windows, etc. (pls also see the attached screenshot).

Sometimes compiz successfully restarts, sometimes it won't do so on the first try, but at least everything will go back to "normal", without compiz. Of course, in some cases, I can't use the panel anymore and therefore only restarting gdm from the command line solves the problem.
