Version: 4.2.13-1 Severity: wishlist fldigi as compiled with fltk 1.3 does not support scaling on high DPI screens, making it hard to read. fltk 1.4 adds high DPI support, which the application needs to enable. Upstream posted a suggested change to the mailing list a few years ago: https://groups.io/g/linuxham/message/47205 . I've tested this here by rebuilding fldigi with the change and linked to fltk 1.4 and it looks good. You can find the change as a well-formed patch here: https://github.com/mmanjos/fldigi-pkgbuild-hidpi/blob/main/hidpi-fix.patch 73, Hamish
