Weird Radeon + Firefox hardware acceleration bug

I upgraded to Catalyst 11.04 and had strange issues with Firefox 4. Viewing a page was like all “fuzzy” or “blurry”. What was strange was as I keep moving my mouse, it got even worse. It was like running the “Blur” filter on Photoshop over and over again till nothing was readable. I decided to disable hardware acceleration and then everything was back normal.

Looks like I wasn’t the only one -> https://bugzilla.mozilla.org/show_bug.cgi?id=653663

Looking over some settings in Catalyst and playing around, I found if I disabled “Morphological filtering” under the “3D Application Settings” the problem disappeared.

Hopefully this gets fixed in the next release of Catalyst.
