User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Build ID: 20120208060813 Steps to reproduce: Visiting http://classic.battle.net/diablo2exp/. Actual results: This results in a garbled page: that is when scrolling everything is mixed like not refreshing. It happens under Mac OS X (10.6 in my case) but not under Linux (Ubuntu 11.10 in my case). Expected results: Should be a correctly rendered page.
Can you try the Firefox safemode http://support.mozilla.com/en-US/kb/Safe+Mode. That disables addons but also the graphic hardware acceleration.

It seems that a new profile doesn't suffer from the problem. After some digging, it turns out that it is caused by some custom print setting that whatever set it. So I'm marking it as resolved/invalid. Sorry for the confusion.

It turns out that only when launching Firefox by opening profile manager (as in `firefox -profilemanager`) that this problem disappears. When opening normally by clicking the icon, no matter whether it is in safe mode or new profile the page is garbled. I have no idea why but hope this information is helpful for the developers.

Also to be more clear, print settings are irrelevant in this issue (I got confused by tweaking the print settings when starting by 'firefox -profilemanager'). Only the way to start firefox matters ('firefox -profilemanager' is fine, while normal start is affected), not the custom config settings, nor profile in use.

The problem occurs on both Stable (10.0.2) and Nightly, but only when layers.acceleration.disabled is set to true. Toggling this back to false and restarting solves the issue for me.

I might have found the problem. It is when Firefox is running in 32-bit mode that causes the problems. When switched back to 64-bit mode it works fine. I marked Firefox to run in 32-bit mode a long time ago to use the quicktime plugin and just remembered it and switched back. However, it is still a problem for 32-bit mode to behave differently.
