I am running Kubuntu 20.04. I have a problem where certain fonts (Courier and Century Schoolbook L) are broken in applications like Inkscape (where they are invisible) or
font-manager where they show like this:
They also don’t show up in Libre office (Don’t really care about this as I rarely touch word-processors).
All broken fonts are
.pfb fonts installed through TeX-live or ghostscript. As the font is already installed I am not able to install TTFs of the font I need. Obviously I do not want to uninstall ghostscript or tex-live as I use them regularly.
I have tried running
sudo fc-cache -f -v
The bug is particularly frustrating as I have existing artwork in inskcape which used courier and Century Schoolbook L.
