I'm currently using a Dell XPS 15 laptop with a 4K display and running
at a resolution of 3840x2160. I've noticed that the problem almost
entirely disappears when I resize the window to a smaller size (roughly
between 1/2 and 1/3 of the screen) instead of being fullscreen. It's
possible that this is only being noticed at higher resolutions.
