xfreerdp full-screen options produces invisible window

[Russell Ault]

Running latest package freerdp-x11 on latest Raspbian Jessie Lite on RPi2 with latest Xorg, fluxbox, and slim from the repositories

Steps to reproduce:
- Install xfreerdp from Raspbian repository (# apt-get install freerdp-x11)
- Run xfreerdp from xterm to connect to an RDP server (both X11RDP and Windows 10 tested) using the fullscreen option ($ xfreerdp /v:rdpserver.domain /f)

Actual results:
- "connected to rdpserver.domain:3389" printed to standard output
- no xfreerdp window opens

Expected results:
- xfreerdp window should open in fullscreen mode

Other information:
- This bug does not appear in the amd64 package for Debian Jessie (i.e. fullscreen worked before I switched my thin client from Debian on an Atom machine to Raspbian on an RPi2)
- xfreerdp will happily exist in fullscreen mode if you start it with /toggle-fullscreen option (and not the /f) and then toggle it into fullscreen mode
- A quick search for the error turned up results on the upstream FreeRDP Bug list, specifically https://github.com/FreeRDP/FreeRDP/issues/2166, although the description of symptoms is slightly different than what I'm experiencing; it has no resolution at this time
