Several apps unreadable characters in title and bars after update Leap 15.0 -> 15.2

I recently updated my machine from Leap 15.0 to 15.2. Most things work fine, but the UI of some apps, e.g. Epiphany and screenshot-tool, now shows unreadable characters (the squares with 4 primitive symbols in them). I tried to solve it loading some more fonts, but that didn’t help, only made the system a bit slower.
I have the impression that the apps affected by this are all GNOME apps, but I’m not sure. I’m running on Plasma/KDE

Any suggestions on how to fix this, or at least where to check?

Check fonts you are using: System Settings -> Fonts.
One-step update is recommended: 15.0 - 15.1 - 15.2.

Please post:

zypper se -si | grep -Ei 'systempack|sytem_pack|system-pack|systempack'

Interesting thing happened. I opened System Settings -> Fonts. When I tried ti switch tabs, it asked me whether I wanted to save changes. I had not made any myself, but I clicked OK, and now the fonts seem to be fine.

Thanks for the advice.:good: Problem solved.

snapce1:~ # zypper se -si | grep -Ei ‘systempack|sytem_pack|system-pack|systempack’
snapce1:~ # echo $?
1
snapce1:~ #

Does this mean a package is missing?

(notice the grep filters on ‘systempack’ twice.)

Note my other reply, the problem seems to be solved now.

  1. no, I would only look, if there are some packages from an older openSUSE Distribution
  2. yes my fault, second should be “system pack” without quotes
  3. Please use Code-Tags for termnial output:

You may well have to, also, execute “fc-cache -f -r -v” both as the user “root” and, for each “normal” user.

  • Please note that, fc-cache complains if the following directories are not present –
    =2]~/.local/share/fonts*
    =2]~/.fonts*
    =2]~/.cache/fontconfig*
    =2]~/.fontconfig*

The user “root” updates the directory /var/cache/fontconfig

KDE changed fonts settings for GNOME apps with updating 15.1 -> 15.2 (and => updating KDE): old text file with settings is no more in use.
ILL sometimes trigger is needed.
