Flash isn't involved. It it caused by Xine with a Xv backend.
While I get it most of the time when fiddling with Chrome tabs at the same time, this is required (just had one without touching anything) and in any case this Chrome doesn't have Flash installed in the first place.
I would entertain a theory that this is an interaction with sound. I had these hangs when playing music in Xine. That displays a light animation in a Xv video and caused these hangs and it went away by hiding the video window.
