[McLovin02]

Hi InfiniteMac users.

I have some problems with screen tearing while watching movies on youtube and some others sites. But not in quicktime.

I don't have screen tearing constantly when i watch a trailer or anything at youtube. But a couples of time, and it kind a annoys me.

So if anyone have any soulution please tell me

- Thanks
