Hi @DrKaraB thank you for your post here on the Zoom Community! This is an unusual problem, I was curious if you have updated recently (Zoom or Windows updates) and then noticed the issue?
Some things we can check
- We recently released a new version of software, 5.9.3 (sounds like you've updated, is this when things changed?)
- in your Zoom Client, it would be good to double check settings for content sharing. You can do this through the Zoom client

Then under the "Share Screen" tab on the left, click "Advanced" at the bottom

I believe these are the settings we need to tweak to see if the condition improves. Especially "Screen Capture Mode" as there are several options.
You can actually leave this settings window open during a meeting even. Change a setting, stop screen share, start again and see if there is a different. If not, stop screen share, make another change, then try again. I believe tweaking these should help, can you please test and let us know?
If this has answered your question to your satisfaction, please click the "Accept as Solution" button below but if not please reply and we can continue the discussion. Thank you!
