I had to uninstall Fedora 32 Workstation KDE Desktop Spin and installed Fedora 32 Workstation Cinnamon Desktop Spin instead. KDE Desktop Spin uses kde5 VCL and has many problems especially with the BASIC IDE of LibreOffice, but Cinnamon Desktop Spin uses gtk3 VCL is OK.
How can we setup Fedora 32 Workstation KDE Desktop Spin to use gtk3 in order to get along well with LibreOffice ?
