Since there are other priorities I stopped looking at this bug for a while.
Here's a couple of things that could help to solve it:
1. It seems to be related to this bug https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1156919
2. It occurs in the motif popups that use the XmCreateFormDialog motif function (I tested nedit, xpdf and a few other motif programs)
