Ubuntu 20.04 Chromium snap fonts missing and become 'boxy'

Question

My fonts stop working randomly in Chromium browser

VERSION="20.04.2 LTS (Focal Fossa)"
Chromium 89.0.4389.72 snap

It goes back to normal when I restart or log back in, but then 1 hour or 5 days later, it breaks again.

I have removed and reinstalled the Chromium snap package, rebuilt the fonts with sudo fc-cache -r -v but still having this issue.

Example screenshot:

I have been following the advices here:

• Snap store does not display characters
• Only squares instead of letters and numbers are displayed in my calculator and other apps in Ubuntu 18.04

But it seems like it keeps breaking again.

Any suggestions on how to fix this permanently?

Answer 1

my friend. You can try to install it in DEB form. In this post, they explain it well. Remember to change the version.

Another alternative is to use Flatpak which is explained in this post as well.

Answer 2

The only way I succeeded in restarting chromium properly displaying the pages was removing all the cache. So

cd ~/snap/chromium/common/.cache
~/snap/chromium/common/.cache$ rm -rf *

Hope this can help also as a hint on what could be the problem.
