Bug Description
Binary package hint: unity
Attempting to use a VNC server, I have discovered that some menus and compiz effects do not work well. Specifically, sometimes Unity's drop-down menus from the top panel do not show up at all, or are incorrectly cropped, as can be seen here:
Other compiz effects are rendered incorrectly, as can be seen below, where the top panel's drop shadow is rendered over a terminal window's title:
Both Vinagre and x11vnc have been tested and found to suffer from the same effects, regardless of the settings used. (Many options to x11vnc have been tried, including the -noxdamage option, which is known to be a required option for using a VNC service to a session running Comiz.)
These effects are not seen in the "Ubuntu Classic (No Effects)" session, where VNC service operates perfectly and as expected.
