Microsoft Teams display issue when sharing whole display

pjfb · 10-13-2025, 09:37 PM

Running MacOS 15.7.1 - MacBook Air M2
Running dual screens on Dell UD22 and my native display with lid open
Just downgraded from MacOS 26 because performance was just awful
Teams 25255.703.3891.5698.

I have an issue when starting to screen share. When I share a whole screen, one or both external displays switch off and all windows move back to the built-in screen. I've tried uninstalling the client, reinstalling. I have plenty of disk space.

Is anyone else experiencing issues?
