STM32CubeProgrammer UI Scaling issue on linux

[Emile BV]

As shown in the picture above, on Fedora 43, the CubeProgrammer application is not matching the OS scaling and there are no options to configure it like in CubeMX. CubeProgrammer is the latest version (v2.22.0), installed today.

My computer is a laptop with a 2256x1504 screen and OS-level scaling is set to 133%. All other applications behave as expected, I only ever have issues with ST’s applications.

This issue has been reported multiple times in the past on different linux distributions. I have tried all suggested fixes in those posts, none worked. Links to other issues that had no solutions:

SOLVED WORKAROUND — Ubuntu/Wayland/HiDPI

I found a working workaround for this issue using system OpenJDK 17 + OpenJFX 11 and forcing JavaFX to use X11 with -Dglass.gtk.uiScale=2.

Tested successfully on Ubuntu with a 3072×1728 / 192 DPI display.

I attached the complete step-by-step solution and launcher script for other Linux users.
