Ubuntu 24.04 font issue

[apelly]

Current Behavior

Post ubuntu upgrade 23.10 -> 24.04 keepassxc fonts used in menus, dialogs, buttons, etc. have changed to some sort of monospaced thing. See pic.

I have googled my arse off, but I can't find a solution to this. I bet it's some unrelated old file/setting that's surfaced from deep in ~/.config or ~/.cache but I have no idea what it might be.

You have some sort of qt variable set or perhaps qt5ct. You should dump your environment variables and look there. Also recommend switching to flatpak.

Looks like you also have the icon with text mode turned on for toolbar. You can change that in application settings.

A few more notes in case someone else ends up here:

Solution

On your advice I found QT_QPA_PLATFORMTHEME=qt5ct in my environment.

qt5ct was installed, apparently as a recommended package for Strawberry music player.

qt5ct installs /etc/X11/Xsession.d/99qt5ct which does export QT_QPA_PLATFORMTHEME=qt5ct

Looking at qt5ct in the GUI, for the first time that I can recall, I see it was showing the font as noto color emoji with no obvious way to reset it to something sane. dpkg-reconfigure didn't fix it, so I purged it, and all is good in the world again.

Kudos

You guys are on the ball! 15 minutes from posting an issue, until you give me a good solution! (Including assigning the issue to the correct project. 🤦‍♂️, sorry about that.) I've been pulling my hair out for two days trying to find my problem.

P.S. I like the words with the icons. Pictures are nearly meaningless to me for some reason.

Hah welcome! Qt5ct used to be great, until it wasn't.
