I just installed Lubuntu 20.04 and with it came libreoffice 184.108.40.206 Build ID 1:6.4.2-0ubuntu3.
When I create a new presentation the first slide is OK. When I create a new, second slide, the letters in the textbox are kind of squished together. So close that it is not readable anymore. This also happens if I open presentations that I created on my Lubuntu 16.04 Laptop.
Are you aware of that issue and will it soon be fixed? Otherwise there is no point in using Lubuntu 20.04 since LibreOffice is cucial for my work.
