Broken UI fonts for Libreoffice flatpak and other applications

[nikostourvas]

Describe the bug

Just updated to Bluefin 39.20240728.0 and Libreoffice UI fonts are broken. Title fonts in secondary windows of firefox (e.g. history window) and thunderbird (e.g. notifications) are also broken. Everything was fine in Bluefin 39.20240721.0.

What did you expect to happen?

All UI elements in application to look properly as they did in the previous bluefin version (39.20240721.0) that I had been using for the past week.

I haven't been able to reproduce this but here's some workarounds people are working with: https://universal-blue.discourse.group/t/encoding-issue-in-bluefin/3281/18

[nikostourvas]

Yeap hadn't seen that, thanks for the quick reply.

Plyply's solution was the only one that worked for me as well, as is suggested in the forum.

`flatpak list`

#Put the AppID in this command.

`flatpak run --command=fc-cache "AppID" -f -v`

[castrojo]

This one seems to be fixing it for folks:

flatpak list --columns=application | xargs -I %s -- flatpak run --command=fc-cache %s -f -v

[castrojo]

OK this should be live for gts users, unfortunately there's some nvidia and -dx skew so I'll need to try to rebuild them again tomorrow.

The fix runs the fc-cache command on the next login in the background.

[castrojo]

Anyone still getting this?

[0xBLERKO]

I am. Tried the suggested command to run fc-cache for apps and the system, no change. I used gnome tweak to change from ubuntu font to default gnome cantarell and that resolved for me. Changing back to ubuntu font recreates the issue. It appears user specific as other user profiles on the same system do not have the font issue and display ubuntu font just fine. Some kind of user font cache not cleared by fc-cache?

edit: I am using latest gts build for dx on a framework laptop. Possible extra factor, I recently restored from Pika backup. Maybe my issue is different?

[0xBLERKO]

I deleted contents of .cache/fontconfig and my user specific issue is resolved. This dir is not included in backup and not cleaned by fc-cache. I have no more font issues for any users.

This was 39 only, closing!
