#136 vcxsrv crash in multiwindow mode

[Chris]

Hi!

I'm experiencing crashes of vcxsrv when using multiwindow mode.

I've tried version 1.20.6.0 supplied with x2goclient on Windows 10 and Windows 7
and version 1.20.9.0 installed standalone in Windows 10.
I've used 1.20.9.0 together with x2goclient as well as with putty and x-forwarding.
All show the crash when using multiwindow option and work without the option, e.g. in "one large window" mode.

Windows Eventlog:

Please find attached packet captures of the X11 network data when starting the application with putty and X-forwarding (without x2go involved).
application-crash.txt is captured when vcxsrv is started with multiwindow mode and application-ok.txt when started in "one large window" mode.

It seems vcxsrv crashes on "Requests: QueryPointer" when in multiwindow mode.

When using x2goclient and removing multiwindow from the commandline options of custom X-Server settings within the x2goclient options settings window, I'm able to start the application in the x2go session without vcxsrv crash.
Sadly, resizing the x2go window, switching to fullscreen or multi-monitor and published applications mode don't work then.

The application is a closed source application. I can test new vcxsrv versions.

Please fix this bug, since resizing, fullscreen or multi-monitor and published-applications modes of x2go are very useful to us.
We would like to use them on windows, too.

Thank you!
