Interesting, I had these issues around 2 years ago with my Nvidia GPU, making Wayland unusable (especially the honestly probably epilepsy-inducing flicker).

After an Nvidia graphics driver release everything cleared up to be very usable (though occasionally stuff still crashed, like once or twice a week). I heavily dislike Nvidia and went with AMD just around a month ago, zero issues.

I'm curious to hear about what hardware you have.
