mplayer freezes with green screen

[ilf]

Binary package hint: mplayer

Version: 2:1.0~rc4~try1.dsfg1-1ubuntu1

After an upgrade from Lucid to Maverick, mplayer started to sometimes freeze.
Immediately when starting to play a video, mplayer outputs no audio, only shows a green screen and even freezes X.
I can't exactly reproduce it, this happens 1 out of 5-10 times I play a video.
It's not limited to a certain file, either.

I had vo=vdpau,xv,x11 in mplayer.conf at first, also tried vo=xv,x11 and now use the default, which uncomments # vo=.
All the same.

Status changed to 'Confirmed' because the bug affects multiple users.

In my case it doesn't exactly freeze but it does lag. I do get the green screen seldom, as you do.

I think sometimes an OSD notification triggers it.
