The font family and font size of
Monos
system fonts
are hard-wired into the
SystemFonts.cs
class.
So if you don't like these defaults, there is no simple way to change them. Not really helpful.
To make things a bit easier,
the patch below
allows you to change these font settings
with a couple of environment variables.

$ mono /opt/keepass/KeePass.exe
