I can easily reproduce the stuttering cursor on GNOME Wayland on all of my systems by doing this:

* move the mouse cursor evenly in a straight motion

* while moving press `Super+a` to open the application list

During the animation, i.e. when GNOME Shell is busy, the mouse cursor noticeably stutters for a moment. On my faster systems it's less apparent but still visible, except when I set the CPU governor to `performance`.

I recently tried the new Ubuntu 22.04 LTS and the mouse stuttering was unbearable while running games via Wine. I had to switch back to Xorg to get rid of it.

Smooth mouse input, especially when using high-DPI mice, is something that's been fixed in GNOME 42 due to release soon.

> Nothing has been done here to avoid potential wayland event queue overflows, as IIUC this is being worked on separately. Although I should probably also mention that this hasn't been seen in the wild during this work.
