I am finding it difficult to fill in forms made with MS Word in LibreOffice. The formatting seems to end up all wrong among other things, and LibreOffice feels slow and clunky to use.
I've tried OnlyOffice, but it tends to crash and be slow as well.
At this moment in time I am trying to get MS Office 2010. Is there a better solution?
Onlyoffice seems to work for me. Which packaging format did you use? (I am using the binary from the AUR) Maybe using a different one solves your problem.
