also, the font is a lot smaller than my system default

its not possible to take a screenshot of the Color Temperature dropdown, but all fields there are shortened to the point of not understanding what they are

Hi, I really appreciate your efforts to point out this issue. Brightness Controller was created using PySide framework, which is reliant on QT4.8 - and has sketchy support on HiDPI resolution.

I am still looking for a workaround though. Meanwhile, can you try installing qt4-settings by the following command:

sudo apt install qt4-qtconfig Yeah, I know, different package and program name. Try changing the GUI settings and font there, maybe?

[allanlaal]

changing font in qt config has no effect on how the text is truncated in Color dropdown

We are now using Qt5, which has great support for HiDPI. Is this issue still there? I don't see any problem on my HiDPI screen on KDE Neon.
