Unity 5.3.2p4 Editor and Game window glitches WAY too much to use.

My Editor and my Game window, the onscreen graphics glitch and stretch and flicker so much I’m unable to use it. I had to go back to P3.Ive made no preference changes to anything from P3 to P4. (MAC)
The only thing that would reset the messed up windows was to RUN the game, and it would reset back to normal.
Oh well, Back to the Future.

Happening to me too. UI is flickering like crazy, incredibly difficult to use.
