I'm on wayland, using whichever version of gnome that come with ubuntu 22.10. Hardware is a 3950x with a radeon 5700xt. That should be more than plenty for being able to render firefox and a couple of electron apps (slack, discord) without stutter. Usually it works fine, but sometimes there is stutter or downright freezes.
Note that it doesn't (currently) crash, the when a freeze happens it goes on for a while (30s?) and then go away.
Your hw is beefier than mine. It could be Wayland (I'm on X11) but it shouldn't because it is designed not to stutter. It should definitely not freeze. Graphic card driver?
Wayland as a protocol may be designed to be stutter-free, but the gnome compositor is very clearly not designed to be that. For example, it will happily request new frames or send new configuration events despite already being behind in processing what the client has produced so far. Which likely will make it fall even further behind, creating a bad circle.
