Not only slow, it drops frames constantly. Doesn’t matter how good your hardware is.
There’s always the Android route, why fix the animations when you can just add high framerate screens to all the hardware to hide the jank. Ah, who am I kidding, Gnome wouldn’t know how to properly support high framerates across multiple monitors either. How many years did fractional scaling take?
Lol, why own up to adding animations the system can’t handle when you can blame app and web devs? Gnome users always know where the blame should be laid, and it’s never Gnome.
