This is known problem, which I have experienced with Windows 8 and 10, remaining unfixed in Fusion 8.1.1. The workaround I found in the forums here is to switch to Full Screen view, then back to Single Window view, which fixes it temporarily. I wish VMware would fix it permanently.
For anyone else following this, VerizonLover also posted the same issue 2 months ago here: Video corruption
(Posting it here as it has a tiny bit more info)
Can you tell us a bit more about your hardware? Specifically the graphics adapter used in your host?
Did you ever install an updated driver for that graphics adapter?
