Really... this seems like a nerd joke. When having a spreadsheet with "Liberation Sans" as font and you change the zoom from 100% to something else, it might happen, that the 5 is turning into a 7... Font size and Zoom Level which "works" 6 - 180% 9 - 120% 10 - 110%
Created attachment 106349 [details] what it looks like
Added version; only tested on Debian Jessie.
The issue is not reproducible in Ubuntu 14.10. That looks like fontconfig nastiness to me. Did you install LibreOffice from official TDF packages (i.e., downloaded from the official website)? If so, you may have an extra copy of the Liberation fonts installed (check it with the command 'fc-list'), which may cause fontconfig to act weirdly (Debian packages are built without LibreOffice-bundled fonts). Please run 'fc-cache -fv' and try again.
I installed LO normally with the package manager. Running 'fc-cache -fv' solved the issue! The fives look normal now. Thanks! - fc-list | grep -i "Liberationsans" -> some results, only in directory /usr/share/fonts/truetype/liberation/ Looks normal, i think :) All related results: /usr/share/fonts/truetype/liberation/LiberationSans-BoldItalic.ttf: Liberation Sans:style=Bold Italic /usr/share/fonts/truetype/liberation/LiberationSans-Bold.ttf: Liberation Sans:style=Bold /usr/share/fonts/truetype/liberation/LiberationSans-Italic.ttf: Liberation Sans:style=Italic /usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf: Liberation Sans:style=Regular
