Kde5 VCL in Fedora 32 Workstation KDE Desktop Spin doesn't work well in LibreOffice

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 ?

Perhaps you should update your Title then to:
“LibreOffice does not work well in F32 KDE Workstation due to KDE5 VCL”
