Yes, these aren't important. Mainly due to still using deprecated
stuff, and not specifying a type explicitly.

If you send me your out-of-tree sources I'll have a look. I suspect a
problem with the build commands (i.e. with libtool) but I'm not sure.

If I run the demo outside the demo directory I get the flickering too.
It is a bit odd. (But I don't think it is a goocanvas problem.)
