Occasional black/blank viewport

Please see the attached video.
In shaded mode, occasionally one of the views turns black it happened with the Front view as well before, [I can see no pattern that leads to that.]

thanks a lot
Akash

i’m seeing the same behavior here but i didn’t report cause i can see no rhyme or reason. seems like it has to do with using the view names at the top of the window to change the view.

mine turns red though.

@Akash, @kleerkoat - can you please run SystemInfo in Rhino and paste the results here?

thanks,
-Pascal

here’s my Sist-Info Pascal
It seems that my Nvida M750 2gb card didn’t make it to the list.

thanks a lot
Akash

@kleerkoat and @Akash Are either of you still having this problem with the Rhino 6 for Mac Beta? Thanks.
