LibreOffice Calc is unusable on macOS

[lomac]

I’ve been using LibreOffice on Linux without issues but on macOS it’s unusable. It keeps on crashing and has multiple bugs that make it unusable. Sometimes when typing in a cell a character being typed replaces the current character so if you want to type the word “hello” you end up with just “o”. Also, I noticed that part of the rows become repeated horizontally, see illustration below:

A B C
1 2 3
D E F
4 5 6
H I J
7 8 9

spreadsheet turns into this:

A B C
1 2 3
D E F D E F D E F D E F D E F D E F D E F D E F D E F D E F D E F D E F
4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6 4 5 6
H I J H I J H I J H I J H I J H I J H I J H I J H I J H I J H I J H I J H I J H I J H I J
7 8 9

It sounds a bit like a graphics issue, in the menu LibreOffice > Preferences > LibreOffice > View try unticking Force Skia software rendering, OK and allow LibreOffice to restart.
