When I move the mouse over anything on the screen it flickers. When I move it across a hyperlink it flickers from an arrow to a hand. This flickering is so quick and constant that it has become an annoyance and is enough to drive me back to using Safari full time. I cant figure out how to stop this. I have deleted and reinstalled a fresh copy of Firefox, but that didnt help. I tried restarting with plug ins off and that didnt stop it.

I want to avoid making significant changes to my environment. I do not have these problems with any other application, nor is this a problem in Safari. It just started and I cant tell if it was due a firefox upgrade or something else. Any other thoughts?
I started to have this problem too after upgrading to Firefox 21.0. It stopped after I disabled hw acceleration. I hope this get solved in the future.
