[X2Go-User] X2Go resizing uncontrollably with KDrive

[Ulrich Sibiller]

If the client side is Windows: Might have to do with the way Windows
adds window decorations. We had an issue like that some years ago
where vcxsrv did it wrong. Since kdrive does not use an intermediate X
server it needs to handle these problems itself. Maybe try to run the
client in Windows 7 compatibility mode. Or change display zoom.
