After installing MATLAB the entire UI was tiny, i used the method described here: https://www.mathworks.com/matlabcentral/answers/406956-does-matlab-support-high-dpi-screens-on-linux#answer_325831
it fixed the matlab window and my simulink model appeared fine too, but when I openes scope it was tiny :(
Sure i can resize the screen but all the text and buttons remain small of course
Here's a reference image, the model is in 119% zoom so you can imagine how small that scope window is.
How can i fix this?
Where can i find more info about tinkering with display settings as described in the linked post?

Hey,
MATLAB on Linux does support HiDPI scaling, but some UI components like Simulink Scope may not scale automatically. This happens because the scope uses Java-based rendering, which doesn’t fully inherit the system DPI settings.
How to fix:
  • Use the environment variable approach described in Does MATLAB support high-DPI screens on Linux? and restart MATLAB.
  • For scopes and similar tools, try enabling Java scaling by setting: Shellexport MATLAB_JAVA=/path/to/javaShow more linesAdjust the scale factor as needed.
  • Alternatively, use MATLAB’s built-in “Custom DPI” setting under Preferences > MATLAB > Fonts for text size.
Hope it helps!
