It doesn't happen every time and I've not spotted any sort of consistency in the when & where of it and the corruption disappears when I take any action that causes re-rendering (closing a tab, reloading the page, etc.). At the URL in this submission you will find a folder containing two example screenshots of this happening (one on the BBC news website and one at the register.co.uk). I've circled the areas of corruption for ease of use. Reproducible: Sometimes Steps to Reproduce: There's no real setup. It just happens sometimes when displaying a web page. There's no rhyme or reason to it that I've been able to spot.

I've browsing almost exclusively with beta 7 since it was released and I've not seen this issue in that version. Whatever was causing the issue seems to have been resolved.
Are you still seeing this with Firefox 4 final?
I haven't seen the problem since beta 7.
