Hi,
I wonder if there is a solution for the small interface issue that Matlab has on HiDPI screen under Linux. It is becoming a real messy working intensively, especially with AppDesigner that suffers also because you cannot change the font size in the editor.
Thanks for the help.

MathWorks suggested the following procedure, which works well for me (R2017b). Quoting from their email:
Tuning a high-DPI Linux system requires two steps
The MATLAB scale factor affects MATLAB desktop and the size/position of windows. The system DPI determines the scale and font size of axes and labels. To set the MATLAB scale factor, please use the following MATLAB commands:
>> s = settings;s.matlab.desktop.DisplayScaleFactor
>> s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5
To calibrate the system DPI to match the scale facto, please use the following terminal commands :
% xdpyinfo | grep resolution
resolution: 96x96 dots per inch
% xrandr --dpi 144
The DPI value chosen should be the resolution found with xdpyinfo multiplied by the MATLAB scale factor that was set. In the example, 96 × 1.5 = 144.
MATLAB must be restarted after Step 2.

Ubuntu 20.04 and matlab 2022b. my 4k monitor is scaled by 200% in the system settings. my resolution is 162x161 dots per inch.
s.matlab.desktop.DisplayScaleFactor.PersonalValue = 2
the GUI and editer looks OK, but the datatips and function hints are still not scaled. you can see from the screenshots, they are very tiny.

I found the issue with this:
One needs to adjust the custum font size for the editor back to, say 12, and then in an open editor window just zoom in by pressing Ctrl + as much as you like.

This worked really well for me on Ubuntu 16.04
>> s = settings;s.matlab.desktop.DisplayScaleFactor
>> s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5
Additionally, I changed font properties in Preferences -> Font to higher font values.

Has this issue been resolved in R2017a?

THis is terrible. Matlab is extremely inconvenient to use with the extremely small symbols.

I recommend you raise the matter as a support case. Any of the volunteers who might happen to know something about the situation would not be permitted to comment about it.

No, unfortunately as of R2016b the issue is not resolved.
