  The VMD GUI (except for Tk windows) are written using FLTK, so
for most of the key windows, the low-level X calls are made by FLTK
and not by VMD itself. On Linux, the VMD graphics window is managed
by VMD itself, so that is the only window where we could add calls to
set the window properties. A useful experiment would be for you to
grab the latest version of FLTK and see if it behaves better with
Ubuntu out-of-the-box (try the sample programs it comes with and
see how they behave). If it has the same issue, then this should be
reported to the FLTK maintainers. Similarly, I would recommend checking
the behavior of the Tcl/Tk toolkit's Tk windows, and see if their code
needs modification as well.
