I'm still convinced GTK 2 is the best X11 toolkit.
Yes I agree with this. Menus on emacs 29.4 is very slow to appear and sometimes hangs X for a few seconds. This is via gtk3 package.
As a test, I compiled emacs 29.4 via pkgsrc using gtk2, no issues and works much faster. I noticed the same on another BSD OS also. The gtk3 version "fails" were the gtk2 version works great.
