Glade renders extremely slow on Mac OS
I've installed glade using homebrew:
brew install glade
according to homebrew this are the versions and dependencies:
$ brew info glade
glade: stable 3.36.0 (bottled)
RAD tool for the GTK+ and GNOME environment
https://glade.gnome.org/
/usr/local/Cellar/glade/3.36.0 (576 files, 15.2MB) *

install: 390 (30 days), 997 (90 days), 3,323 (365 days)
install-on-request: 361 (30 days), 940 (90 days), 3,111 (365 days)
build-error: 0 (30 days)
How to reproduce
- Open glade
- Try to do anything inside it or move window around
My impression is that it's not glade itself to blame here, but perhaps either GTK3 or Cairo, or maybe there is the need to "enable" some hardware acceleration rendering type of support that wasn't enabled on Mac OS.
