Morning,
I have similar problem – after connecting Windows11 to Mac OS (macbook air m4),
On client window (Windows11) I can see only menu from current app. (for instance NoMachine), and only part of background.
When using mouse buttons, they work on mac, but no result on Win11 window, even when I change to other app., menu/top bar – from NoMachine still persist.
On Mac – I can see properly working mouse button work.
I did try with <span style="background-color: #f9f9f9; color: #666666; font-family: Inconsolata, Consolas, Monaco, 'Lucida Console', monospace; font-size: 13px;">DisplayServerExtraOptions "-nosckgrab"</span>
did not help.
I did check a few resolutions, and screen size (from full / full_all screens (4 i have laptop+3xLCD)… to minimize completely)
I did try reinstalling and it is working now… (it worked during writing post, so I am not deleting it)
So still no solution find for problem, then reinstalling.
Best wishes,
Jan
