The patched version of #Mutter + #GNOME Shell I've been running for the last few days, while profiling with @YaLTeR, is _crazy_ fast.
This is the first time in *13 years* that my GNOME Shell isn't slowing down after a few hours/days. Even _without_ triple-buffering.
It is so smooth, I can't stop moving windows around just to savor how unreal it feels. Turns out I never experienced 60 fps (with & without #Wayland) in GNOME in my life, until this week.
I ought to blog about this.
