By setting:
export QT_XCB_FORCE_SOFTWARE_OPENGL = 1
export LIBGL_ALWAYS_SOFTWARE=1

I have KDE running in an x2go session in my F22 test system (installed 
from the development/22 tree) but there is no panel visible.

kscreen was resizing my x2go window after a few seconds and xdpyinfo was 
reporting it as 1920x1080. I have removed the kcreen package and the 
x2go window is now no longer resized and is reported by xdpyinfo as 
800x600 which is what I asked for in the xc2go client.

Now the panel comes up and is visible, but only for a short while and 
before disappearing.

plasmashell is still running so I'm guessing that the panel was 
relocated off the display window somewhere.

Resizing the x2go window in order to look for the missing panel does not 
reveal anything and causes a black border around the desktop background 
where the window has been enlarged.

After a minute or so the konsole, which was started as part of the 
session, disappears, but the konsole process is still running, so maybe 
it got relocated elsewhere too.

Any ideas on how to find my panel or stop it moving or any insight on 
whats happening would be appreciated.

Thanks
