HiDPI Screen Environment Variables

Many application won’t detect DPI and still counts on 72 or 96 DPI. So the text on 27” 4k diplay will be very small. I with there was more systemic solution, because now it sometimes work, sometimes need to set variables with different scaling. Also the text size is different across apps even with a support for high DPI.

  • export QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCALE_FACTOR=2 - for Qt applications like LMMS
