Binary package hint: compiz
I noticed this bug with Chrome. Chrome displays a tooltip of the page title when you hover the mouse on a tab. It does not wrap the title so it displays all on one line. Some pages I had open had really long titles (the whole long web address of the page). Whenever I hovered for a tooltip, Compiz kind of quits. Chrome goes fullscreen and won't go back to normal. It actually seems like Compiz falls back to Metacity. The window manager stuff is still there, just without compositing and effects. When run in a terminal, this is what Compiz says:
Window manager warning: Treating resize request of legacy application 0x320006d (http://air) as a fullscreen request
It doesn't crash, it just "falls back." And doing Ctrl+C in the terminal really does kill Compiz (always an adventure).
I do think that Chrome should handle the tooltips better (Firefox wraps the same long titles), but Compiz should also handle this kind of event better.
I can get logs/screenshots if necessary.

Hmm, that message is actually from metacity so at that point compiz is already gone and it is metacity deciding to make chrome fullscreen (probably because of how it handles the tooltip). Things like this make it obvious we need a --debug flag for compiz so it doesn't fall back to metacity and properly crashes so we can see why.
