I find it frankly kind of embarrassing that this still doesn't work.
At very least there should be some kind of text around enabling
desktop effects that tells you that VNC will not work properly.  This
functionality worked a few versions ago using both binary and open
source drivers, but has since become broken for all of the above.  At
one point I was able to see that the fix wasn't being applied to a
second monitor, but other than that it worked, now it just doesn't
work if you have desktop effects enabled.  I would think enabling
desktop effects should disable VNC or present a message at least if
this is never planned on being fixed.
