Well, this is quite odd.

I'm not sure I believe the "doesn't work at all on Windows 11" theory, 
since I'd think we'd be hearing more about it, but something's not right.

You might try with '-logverbose 3', which might give a little more 
information about how far it's getting.

I don't know what else to suggest apart from maybe stepping through the 
code with gdb (install the xorg-server-debuginfo package as well) to see 
where it's getting lost...
