Got worse the last 15. update - but I had found a workaround (by ensuring OpenGL app didn't start up in full screen mode) - but now I get corrupt display. This all used to work perfectly in earlier 15 version. And I just paid for the upgrade for 16 - will be seeking a refund...
Problems here also with Open GL on PD16 with Catalina. Just returning to PD15 where it was ok for me. Issue is corrupt display. This is with Win 10.
