Details:
Dear Octave developers,
This probably a feature request - at least not a /severe/ bug:
I'm running ArchLinux with KDE Plasma on a 15" UHD laptop display (3840x2160
px). In order to have readable fonts I configured a scaling factor of 2 in the
KDE settings.
While Octave's Qt GUI performs great on the HiDPI display, the output
generated in the different plotting windows (both, Qt and FLTK) remains
unscaled, i.e. tiny/almost unreadable (see attached screenshot). In addition,
plot(...) on graphics_toolkit('qt') results in a small plot sitting in the
lower/left quarter of the figure window.
The plotting subsystem should adjust line thickness, font sizes, and the
overall size of the plot in order to match the display's scaling factor.
Thank you for creating this great software.
Please, let me know if I can help (e.g. by trying out some patches)
Regards, Michael
