Full screen PIP window issues - window cannot be closed, stopping stream results in blank space, some other interaction (minimize etc) may cause crash #5155
Description
Users having trouble exiting a full screen PIP window - upon moving the mouse to the top of the screen, the normal window controls don't seem to appear. This is not how it used to work.
Also, according to some reports a residual blank space may remain after the PIP stream is closed (note: there is some difficulty recreating the issue).
