It works!! (pyQt, PySide, vlc all work now). That was the fix that was needed and will report this to the package maintainers. Regarding your assumption, it is actually incorrect. I do not have Xinerama checked as an option in my session profile (it is unchecked) so that had no bearing on the issue rearing itself.
