few seconds, then output window stops updating. Console continues playing
on though.

I think the window is "moving" for some reason, and it's not responding to
that. I wonder if the fix is to just integrate with "real" ffplay, but
anyway this one reproduces quite easily in windows, just drag the window
anywhere and output freezes, basically.
