Lights Out causes problems with Zoom conferencing app

A friend of mine and I just ran a test Zoom session, and we verified that Lights Out and the Zoom app don't work correctly together, at least on Macs:

1 If you share the Lr window in Zoom and use Lights Out in Lr, everyone else will see a blank, white image area thereafter. The same result holds even if you used Lights Out sometime before the Zoom session: Using Lights Out permanently poisons the running Lr app. Quitting/restarting Lr fixes the problem. (Quitting/rejoining the Zoom meeting doesn't help.)

2 If you share your desktop in Zoom, Lr always displays correctly, including if you use Lights Out before or during the Zoom session.

Therefore, it is best to share your desktop in Zoom to avoid Lr problems. Just remember to hide anything confidential before you share.

Windows to Windows doesn't seem to have this issue.  Rob and I will be testing sharing on Windows with viewing on Mac and vice-versa.  Rob will update post with results.  Will also see if use of Graphics processor has any effect.

The problem only occurs if you are sharing the Lr window from a Mac. There is no problem if you share your desktop.

Turning off the graphics accelerator in Lr Preferences makes no difference.
