I can't reproduce this. Perhaps this was already fixed in the new build?

It seems to only happen when "layers.accelerate-all" is set to true in about:config .

I'm still unable to reproduce it. If you haven't already, update your copy of Firefox.

Press Alt -> Help -> Check For Updates...

I checked and it found no new updates. I will see if it is a problem with an addon.

I've done some testing. 

1. I downloaded the latest nightly directly from the ftp to be sure. Didn't change anything.
2. Disabled all addons. No change.
3. Tried using a new profile. It seems there are two settings that must be changed to reproduce the bug. 

First you have to have "mozilla.widget.render-mode" set to -1(should be the default) or 6. "layers.accelerate-all" must be set to true.
