That would be after the next keyframe.
Something goes wrong decoding.
I would normally suspect something like -hardframedrop, but then it wouldn't always appear at the same place.
And a faster CPU should rather cause it to go away.

We have no relation with MPlayer2, it is a (to my knowledge inactive) fork.
I'd suggest trying MPlayer compiled from sources.
For trying out at least, ffplay/ffmpeg support VDPAU as well, though in a different way.
Or as a MPlayer fork (that is different in lot of ways, but still shares a good bit of code and thus useful to test) there is also mpv.
