I use LibreOffice Writer 22.214.171.124 on Ubuntu 17.
I’m having trouble with the space around Greek letters in formulas.
Horizontally there is too much space, for instance after a Greek capital delta. (what should look like Δt looks like Δ t)
Vertically there is not enough space. A Greek letter in a fraction is almost glued to the fraction bar. When I increase the space around fraction bars the Greek letter moves, but so do all the non-Greek letters and numbers which were in the correct position.
Any suggestions how I can solve this?
