[X2Go-Dev] Bug#1276: VcXsrv windows xserver crashes when trying to resume a fullscreen session

[x***@0bl.net]

I have the same problem even with a single monitor system.

Environment:
- x2goserver 4.1.0.0 (ArchLinux)
- Client: Windows 10 Build 1709
- Desktop: xfce4

Steps to reproduce:

- Open Windows client (4.1.1.1), start a new session with "Connect to local desktop" (resolution does not seem to matter, but I'm using windowed 1650x1010)
- Click "Full access"
- As soon as the "New session" window appears, x2goclient crashes.

Older versions of both the client and server (tried different hardware/distros on the server also) exhibit the same issue.

Backtrace from Dr. Mingw of the debug exe:

vcxsrv.exe caused an Access Violation at location 000000006E34F608 in module MSVCR120.dll Reading from location 0000000006E04648.

This looks like a bug in vcxsrv. You could try to run an other x server on
Windows (settings menu in the x2go client). Or download the current vcxsrv
1.19.something from SourceForge.
