Re: Firefox testing - offscreen surfaces and OMTC
I'm seeing flickering (e.g. with arstechnica) on 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV620/M82 [Mobility Radeon HD 3450/3470] with native drivers (F22). I have seen heavy flickering on mapy.cz (online maps) when zooming. The longer I used the browser, the more it seemed to flicker.
