Optimize video when sharing shows black boxes

[mandiASME]

After the latest update I’ve noticed that the share screen video optimization was enabled which displayed black boxes for the attendees of the zoom photo gallery.  Is this a known change or issue reported?

Hello @mandiASME,

There are several reasons why the display shows a black screen or boxes while screen sharing.

when screen sharing the entire desktop the zoom windows such as the chat box and participants photo gallery appear shaded when viewed by the participants.  This only started recently.  Is this related to a new update?  When I disable video sharing optimization the issue is resolved. But I’d like to understand the root cause.
