File picker (choose file) GUI bug

Normally, the file picker (or choose file) window works fine, but in some applications like notion, and rambox it has a bug and does not show the file names, please see the attached screenshot.


This is a common problem with Snaps. To fix it you need to clear the font cache.

Either easy and automated:

fc-cache -r

And/or manually delete the fontconfig cache directory in your home folder:

rm ~/.cache/fontconfig/*

And possibly the system cache too:

sudo rm -f /var/cache/fontconfig/*

Hope that helps!
