I've just upgraded my openSUSE to 12.1, which ships with gnome3. Previously, I had gnome2 running with vino-server as a vnc server that starts upon login. With gnome3 this works too, but the vnc session itself is broken. Images / windows / fonts flicker or are only partially visible. I highly blame this on the 3D effects or 2D drawing animations, which are not very healthy for vnc.
What can be done to disable all these effects? Or is there a way to fix VNC?
