(This is the same reply I sent when Robert emailed cygwin-xfree rather
than cygwin.)

I have been using Cygwin/X on Windows 10 64-bit without issue, across
numerous builds (currently 10240 also.)

The 2nd time you ran startxwin, It looks like Cygwin thinks you lack
3D acceleration. Try this command:
$ startxwin -- -extension GLX -multiwindow

Also, the "UnknownGroup" might be an issue that prevented you from
writing the lock file to /tmp/. Someone else would know better than me
