The seek bar (timer) has considerable lag...speeds up and slows down, doesn't seem to know where I am in the clip precisely. Wonder if that is related to anything.

That one I seeked somewhere, used alt+enter to full and alt+enter again to window and closed (no pauses)

I did the same thing here (smaller log file)
It doesn't consistently do this with alt+enter, just seems to have a lot of cases of just ok switching or much worse
