Package: x2goclient Version: 4.0.5.1

When connecting in single application mode, and you move the window by dragging the title bar, the app freezes. If you have two windows open, you see on the windows behind the top window a very slow repaint (up to a minute, depends on how long you moved the window before). After repaint, the app works again.

This issue does not happen, if you maximize/restore the window or move them to another monitor via keyboard shortcut.

Please see the attachment. I moved the xterm from the middle to the right, i took the screenshot while the very long repaint process.

With this bug, the single app mode is nearly useless.

I'm using XFCE4 on Arch Linux.
