All buttons gone, all menus and words gone

[AndrewL]

I am running kubuntu 18-04
After a recent update, or possibly configuration change, I am no longer able to see any icons or words apart from the title bar. It goes to a file recovery window first, then to the main application when I close the file recovery window.
I have completely removed, including configuration files, all packages with “Libreoffice” in the name, and then reinstalled all of libreoffice.
No change.
I have gone into system settings and disabled “Enable compositor on startup”, and rebooted. No change.
I suspect it is a graphics problem, but I cannot see anything in Libreoffice so I am unable to change it back.

Any clues ?

I found the answer.
Completely remove, including configuration files, all packages with “Libreoffice” in the name.
Manually delete the following folder;
/home/andrew/.config/libreoffice
Reinstall everything and it now works again.
