  This issue has been discussed previously. VMD depends on the underlying
FLTK and Tk graphical interface toolkits for rendering of all of the GUI
widgets. Preliminary support for high-DPI displays exists for MacOS X
in both of these toolkits, but high-DPI support is still ongoing work on
Unix/Linux X-Windows and Microsoft Windows platforms last I checked several
months ago. I will continue to revisit this issue, and as soon as there
appears to be a viable FLTK+Tk combination that works on the other non-MacOS
platforms, I will be happy to make test builds of VMD available with
high-DPI support on these platforms. As soon as I have something I can
share, I will let VMD-L know.

Best regards,
  John Stone
