ubuntu 24.04 zoom 6.1 minimized won't expand to show full meeting window

[OpenPrivacy]

Everything worked in ubuntu 22.04.5 LTS and zoom 6.1.6.

Upgraded to ubuntu 24.04.1 and have one major issue: when I minimize the zoom window to a floating thumbnail, I can't restore the full size window.  Mousing over the double arrows (bottom right) I get "Show full meeting window" but clicking only causes the thumbnail to blink.

I have tried rebooting, upgrading to the newest zoom 6.1.11, and removing .config/zoom.conf & .config/zoomus.conf

Current system:

• zoom 6.1.11
• ubuntu 24.04.1 LTS
• thinkpad x1 carbon gen11

More info: I removed zoom 6.1.11 (sudo apt remove zoom) and installed zoom 6.0.12 with snap (sudo snap install zoom-client) -- the older version restores the full meeting window properly. Then I removed the snap version 6.0.12 and reinstalled the deb package 6.1.11  - the restore full meeting window process is broken again.

So this appears to be a problem with zoom 6.1.x and ubuntu 24.04.1

Looking for help/suggestions as I'd like to remain on the newest stable version.
