After few more tests: 
- when I move video window to rotated screen as soon as wideo would switch to that monitor it (whole rotated monitor) turns grey. 
- moving video window back doesn't restore propper operation 
- rest of X works for a few more seconds or until I close mplayer whichever is first then freeze

So it's rather not vblank issue any more.
I also tried with your last patch Barry: "Fix segv for clipped movie window". Didn't help on that particular issue.
