Question
What is going on here?

This is randomly happening at the moment. Its doing it occasionally on clips from different cameras. This one is only doing it when set to 1/2 res. Full res and 1/4 res play fine. It is stretching and grainifying the clip. (what it should look like below). I think it might have started after a windows update, but I cant be sure. Display driver version 560.94
