When rdesktop 1.7.1 client connects to xrdp 0.6.0 and is scaled to or from the full screen mode a black screen appears. When parts of the screen are updated they are creating a brush-like effect.
If rdesktop connects to windows rdp server - no problem
if windows rdp connects to xrdp - no problem
if rdesktop connects to xrdp - brush screen
see the attachment - a brush screen produced by chromium moved around the black screen after exit from the full screen mode
