How to change main UI interface font (Linux Flatpak version) -- Feature Request?

Current MusicBrainz Picard version: Version 2.13.3 as a Flatpak.

Host: KDE-Neon Kernel: 6.11.0-26-generic arch: x86_64 bits: 64
Desktop: KDE Plasma v: 6.3.5 Distro: KDE neon 24.04 6.3 noble
Qt: 5.15.16
KDE Frameworks: 5.116.0
kf5-config: 1.0

Hi – a number of Flatpak versions ago of this MusicBrainz Picard software, there was apparently a change made that seems to have affected the default (and fixed) font size of the main UI interface screen.

Originally, on my KDE Neon Plasma desktop (Linux), the font was large enough to be easily read. But since the change noted above, the font of the main screen is now too small (still readable, but too small to be comfortable).

I checked all of Picard’s settings options for a way to change the underlying font, but I don’t see anything that could help. Also, perhaps because the version I’m using is a Flatpak, there’s no Picard.ini" file to review and edit, nor anything useful in my ~.config/ subdirectory either.

So if indeed this is not currently possible, how do I make this a new feature request, so that future MusicBrainz Picard Flatpak versions will indeed allow me to change the underlying default font to something larger?

Thanks.

I’m guessing you’re on Wayland using fractional scaling, but you could try launching the application from the terminal with the following command, which will temporarily change the app’s scaling (make sure you don’t have any other instances of Picard running):

env QT_SCALE_FACTOR=1.25 flatpak run org.musicbrainz.Picard

Note that this will affect all window elements such as icons.

If you’re happy with the results, you can modify the .desktop file to always start with this flag enabled, or add it as an environment variable in ~/.bashrc.

Hi - thanks for the reply. Actually, I’m running x11, not Wayland, because one of my linux applications will only run under the x11 windowing system. Does this affect your previous tip, and/or suggest any other things to try?

Ah, nah, I’m stuck on X11 myself due to accessibility issues. The command above works on both (just tested) so I’d say give that a shot first before going down the rabbit hole of runtime issues.

I don’t know which change to the Flatpak version might have changed how fon’t size or fractional scaling is handled.

But generally the Flatpak version is kindly maintained by Lctrs on GitHub - flathub/org.musicbrainz.Picard . Maybe open an issue there.
