OpenGL apps broken AGAIN in v 16

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...

 

I reported Open GL as having problems with V16 beta quite a time ago. No change there then...

 

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.

 

Any updates on the Open GL issue? It is really annoying... Have to move back to PD15.
