Heh.. was feeling smug until I discovered -extension XFIXES had already been suggested at the end of this thread! I've been working around with -extension XFIXES. I came across this bug looking to see if the one I'm about to file regarding a Segfault in VNC is a dup.
I discovered this debugging the vnc server, and have some comments from RealVNC who I originally contacted: """ Firstly, VNC Free Edition 4.1.1 has a serious security issue and should not be used on any un-trusted network - VNC Free Edition 4.1.2 resolves this issue. Secondly, VNC Free Edition does not provide the Xfixes extension. From the patches filename you have included below, it looks like Ubuntu is using a custom VNC Free Edition 4.1.1-based package, which is build against a different version of the X server, and so does provide Xfixes. The two potential solutions I'd propose are: 1. Upgrade to the standard VNC Free Edition 4.1.2 package, which will not provide Xfixes and so presumably won't confuse GTK. OR 2. Find the run-time option to the Ubuntu VNC-based Xvnc to disable Xfixes support in the X server, again to avoid GTK being confused. The problem could be in the Ubuntu VNC-based X server build, advertising Xfixes but not properly supporting it, or in GTK in detecting Xfixes and then making invalid calls to use it, but it's impossible to say which. In either case, the packages you're using will have been patched by the Debian guys, so in the first instance it's worth reporting the issue to them - the package maintainers can then propagate the report if it turns out to be an issue with the underlying software.
