Comment 3 for bug 662565

I've just tried running Firefox with -safe-mode . This bug is still occurring, so it can't be an add-on causing the problem.

Should this problem be reported upstream to Mozilla? Unless it's a problem with the window manager/Compiz. However, Nautilus, for example, doesn't seem to have this problem.

Also, I'm happy to provide any debug info if required.

This problem could be affecting other people who simply haven't noticed - it's quite easy to miss.
