Looks like another duplicate of #4058

[harry-xm]

I can connect and use Xpra normally if I use Cmd+Tab to switch between windows instead of clicking icons in dock. No server error is reported, so I think it's a different issue.

[totaam]

Different symptom but likely the same cause.

[garankonic]

I confirm that I do see this issue on M1 Pro Mac with Intel build of the XPRA. The other bug mentioned in this thread I also see but with the Arm64 build of the XPRA

[bmmund]

Seeing this on an intel based mac as well.

My bet is on https://github.com/Xpra-org/gtk-osx-build/issues/27

[totaam]

Likely "fixed" as per #4357
