Hi Itamar,
Have you compiled PyMOL yourself? If yes, have you installed PyQt5?
See https://pymolwiki.org/index.php/Linux_Install#Requirements
When 2.3.0a was built on Linux using the wiki's build method there were
no issues getting it to pick up PyQt. However, a build on mingw64 on
Windows7, which was pretty much the exact same set of build commands
lightly edited to fit that environment, just could not find/start PyQt,
and it always fell back to Tk/Tcl when it started. Something about how
Python is picking up PyQt is working differently on the two platforms.
(Possibly there is some configuration file that should be modified under
Windows, and it was not.) Since the Tk/Tcl version still works fine I
gave up and left it at that.
One thing though - Qt takes up a ridiculous amount of disk space
compared to Tk/Tcl. That isn't so obvious on linux because the Qt
pieces are sitting in system directories, but with PyMol on Windows
where copies must be inside any distribution directory, one can see just
how huge all the Qt files are. Having run Pymol under both interfaces
it isn't at all clear to me what Qt offers to offset that bloat - I see
the fused windows, a very slight change in the GUI look, and a slightly
slower launch. There must be something about Qt that is a significant
improvement over Tk/Tcl - where/what is that?
