Ever since I installed Windows 7 64-bit, I have been getting a strange visual glitch in the centre of a lot (but not all) of the online flash videos I view.
The glitch is a flashing transparent square that appears to show in between video frames in the centre of the video. You can only see it by its outline but its big enough to cause constant annoyance.
Bizzarely enough the square dissappears if the video is put into fullscreen and doesn't appear all videos, only the majority.
I have the latest flash player installed and the latest catalyst drivers
for my Radeon 4980, but the glitch persists in both 32-bit Firefox and Internet Explorer.
Any help or advice on this would be greatly appreciated.
