I've found no suggestions that seems to apply to my case so I haven't tried anything.

  • I see same. 90%of time I can solve by using keyboard shortcuts to change from one workspace to another. After one or two changes, thr video rights itself. If you don't have keys for tgat. Learn how to define them. – pauljohn32 Oct 29 '18 at 3:10
