I have a problem if I use the RibbonWindow for hosting my Ribbon, WindowsFormsHost and other Controls (statusbar, no Docking) and an active VNC connection is present (modified UltraVNC Server using MirrorDriver, I don't have access to the source).
If an VNC connection is active, the WindowsFormsHost output (OpenGL Rendering) is not fluent on the host(VNC Server). But on the client it is.
The screen area of the WindowsFormsHost seems to be only updated after some focus change (on the vnc host).
If I change the RibbonWindow to "normal" WPF Window its working fine. Rotation of OpenGL scene works as expeted on both (host and server) while VNC connection is active.
Can you imagine where this comes from? I woul really like to use the RibbonWindow because of the better visual appearence etc.
