[Using Linux Mint 19.2, LO via Flatpak]
I have not been able to upgrade LO above version 6.2.5.2 because the rows/fonts just aren’t being displayed properly. I had thought that this was an issue with Flatpak, but installed via the Ubuntu PPA caused the same problem.
Here are screenshots of what I’m experiencing. What I’m most concerned about are the almost unreadable row numbers (all washed out in dark grey); the font looks horrible:
Bad:
Good:
I’ve tried changing fonts (current font is Font-Awesome), even going back to the default Liberation Sans, but it doesn’t help. On another note, my spreadsheets load extremely slow on 6.3 and above, whereas 6.2 loads almost instantly.
Here is one of my spreadsheets, as requested: test.ods
