I can confirm this issue. Unfortunately I cannot provide good information on when it occurs, as I can often use firefox heavily in a session without it occuring. I removed my ~/.mozilla folder some time ago and started fresh, but the issue still occurs, so it's not a problem from there. I have only experienced this with firefox. It seems to happen when starting the program (I cannot remember/reproduce it happening at other times atm). Minimising/maximising resolves the issue for me.
