There is a discussion of this problem here:
http://ubuntuforums.org/showthread.php?t=1383356&page=2
It has been seen with a number of vnc viewers (not just vinagre) and
appears to be a problem with xdamage extensions. From post 15 by
v_2ryann :
Here is the answer guys, on how to do it without changing the
effects:
1) Open a terminal o press ALT+F2, then run/type: gconf-editor
2) Go to /desktop/gnome/remote_access and enable "disable_xdamage"
I found it found here:
http://swiss.ubuntuforums.org/showthread.php?t=1496368
The gconf-editor says this about the XDamage extension of X.org: "This
extension does not work properly on some video drivers when using 3D
effects. Disabling it will make vino work on these environments with a
slower rendering as side effect. "
One post suggested a possible link with nvida drivers, but my machine
does has ati drivers and experiences the same problem. Many people on
the forum thread above (and others) have said turning off desktop visual
effects (which presumably use xdamage) solves the problem.
