[Bf-committers] Automatic DPI detection issues

[Brecht Van Lommel]

As mentioned in the commit log, the UI Scale setting in the Interface tab
can be used, doesn't that work?

If you look at the equivalent settings for Windows/macOS/Gnome/Unity/..
they also offer a scale or percentage. I see no reason to show the absolute
DPI.

Linux doesn't have a single window manager standard for specifying DPI, but
we use the same convention as Chrome or Firefox which works in many window
managers, it certainly isn't random. Are you saying the DPI is not being
detect correctly on your system, while it works in other applications?
Perhaps we can fix that?
