I switched from an old radeon 4850 to a gfx 660.
I formatted windows 7 64bit.
I am using default settings in the latest VLC.
Now movies in VLC often have weird horizontal lines. The same effect happens in fullscreen youtube videos.
This was not there before, when I had Radeon. Playback with verbose 2 does not reveal anything other than a lot of "Mouse hidden/shown" events. When I play the exact same files in Windows Media Player the horizontal lines are not there.
I have googled the crap out of the problem, and searched the first few pages of a search on this forum without finding a solution that worked. Any help would be greatly appreciated. I think it's weird that youtube flash videos and VLC share the same problem, yet it doesn't happen in WMP.
