font size, UI & DPI

[farvardin]

I'm trying to use Muse on my 14" screen (1920x1080). I've set the DPI on my system (mate) to 140, on other applications it looks ok, but on Muse everything is so tiny.

I have a "Qt5 parameters" which allows to change the default font size for applications. I've set it to 16. But on muse I can't even change the "system font size". In addition icons are very small as well. I can't see my screen to HiDPI because everything would look too cramped on it (I've tried this but came back to normal DPI)
