I have been using LibreOffice on and off for a few years now and generally I think it is a great alternative to the MS Office offering. It does the tasks that are required and the improvements over different versions have been steady and useful
I had however a very strange experience in which dialogue boxes and other windows such as alerts and messages just showed blank text. It was obvious that there was some important information in them, but it was not possible to read them. In some cases it was ok… I mean I knew here the “OK” button was expected to appear, or where “Cancel” should be placed. However, it was an annoying (at best) and limiting (at worst) exoperience.
After digging in a bit I realised what the problem was. The fonts that were supposed to be showing were at fault. The culprits were as follows:
- DINRegular.ttf, and
- DINRegularAlternate.ttf
After removing these two fonts from ~/Library/Fonts/ everything went back to normal. I hope this helps in case you are having a similar issue.
