I guess that the xfreerdp just creates a window that is large enough and positioned in a way that hides the window borders. However, Qubes OS AFAIK does not allow the positioning for security reasons. However, you can do this yourself. It depends on your desktop environment and configuration, there is rough howto for Xfce:
* Adjust the window position by alt+left-click and movement. * Adjust the window size by alt+right-click and movement. * If needed, make the window always-on-top by Alt+Space and selecting Always on Top. I am pretty sure this can be automated by xdotool or something similar.
