I am compiling Emacs 27.1 on a RHEL8 Linux box. This RHEL system is a remote system I log in from my Windows machine using MobaXterm (Personal Edition V12.1) on the Windows machine as X server.
On this new-ish RHEL system GTk2 and GTK3 is installed. On other Unix machines with older OSes I use GTK2 for Emacs. Is it better to use GTK3 which is available to me on the RHEL8 system?
