So, I bought myself a new system a couple days ago. It seems like I've got everything running smooth now except this little problem.
When I run flashplayer, or a youtube-clip (don't know what player that is) and view it in fullscreen, it freezes the picture after a while. The sound is still there, and if I minimize the view it works just fine. If I go back to fullscreen after minimizing, it all starts over. I've tried different drivers.
It works just fine with fullscreen in mediaplayer and such.
