Running on Xubuntu 18.04 via repo http://ppa.launchpad.net/libreoffice/ppa/ubuntu bionic main
I tried the following:
- disabling anti-aliasing options as suggested on Askubuntu
- disabling all Graphics Output and Font Lists options under Options/View
- starting in Safe Mode
- deleting the folder ~/.config/libreoffice/
- installing the OpenJDK JRE (
default-jrepackage, initially I didn’t have any JRE installed)
Writer and Calc are working fine as far as I’m aware (though I’m not a heavy user), Math at least opens and seems operational.
I’m not sure how to debug this further.
