Hi,

besides the tests reported above, on the pc where I was experiencing the problem (with Ubuntu 20.04) I switched to the .deb version, which always worked perfectly.

Today I tried to install the DBeaver snap on another (older) pc, this time running:

snap    2.46.1+18.04
snapd   2.46.1+18.04
series  16
ubuntu  18.04
kernel  4.15.0-118-generic

I experienced the same problem, so I remembered of another issue that happened to me recently: https://github.com/snapcrafters/gimp/issues/122#issuecomment-691476359

Applying the same workaround fixed the problem on this pc. No more errors and square fonts.

For the record:

sudo rm /var/cache/fontconfig/*
rm ~/.cache/fontconfig/*
fc-cache -r
sudo fc-cache -r

I’ll let you know if the same works also on the 20.04 pc.

This also worked for me! Turns out I messed things up when installing new fonts.
