I have a computer with an nVidia video card, using proprietary drivers. I experience this issue.
I have to add that after a suspend/resume cycle my videos playback slowly if they are enlarged, but normally when there's a 1:1 relation between display pixels and video pixels, meaning that hardware accelerated video resizing isn't working properly. I hope this information may be useful to diagnose this issue.

Reloading compiz fixes the issue.
