I am currently running LMMS on my Lenovo T540p with a 2880x1620 resolution screen and it is seriously starting to give my eyes a work out. Is there a compile flag or something I can do to make LMMS scale better to my screen resolution? I realize that I can just set the resolution lower, but I would like to find a better solution.
I think this is an issue that has come up before. I could be mistaken. It certainly is a problem with LMMS currently. I don't believe the current version supports scaling. It would have to be modified in the source code to use style-sheets or something like that, I think.
If you're using Windows, you could try pressing (<Windows logo key> + <=>) to pull up the Windows Magnifier. Modify the settings to only increase by 25% when zooming in/out... The magnification will then follow your mouse around. Maybe that'd be a temporary solutions to help your eyes?
