Also, regarding the mouse cursor stuttering/lag:
The issue also is visible when running GNOME Shell on Wayland and having the Dash to Panel extension ( https://extensions.gnome.org/extension/1160/dash-to-panel/ ) installed.
When you move the mouse cursor over the panel, the cursor starts to slow down.
Once you move the mouse cursor outside of the panel, the cursor speeds up again, i.e. is no longer laggy.
It only occurs on Wayland, not on X11.
