Weird screen corruption with Firefox 16.02 with hardware acceleration switched on. iMac 11,1 Intel Core i7 2.8 GHz running OSX 10.6.8 with ATI Radeon HD 4850 display hardware.

Some bizarre effects like a surround on two sides (top and right) of main Firefox window with elements captured from the top and side of main screen which on occasions flash at high speed and also a mouse focal point offset

I've tried Firefox safe mode and extensions plugins disabled and it definitely seems to be caused by switching hardware acceleration on as problems disappear when switched off.

Never had this problem before in several years use of Firefox until 16.02

If hardware acceleration in Firefox isn't working properly then you will have to leave it disabled.

Thanks for the link. Has something changed in FF v16.02 hardware acceleration that you are aware of that might have caused this?
