That is pretty interesting! Does M1 do some kind of variable vsync based on input? 😲

I tried it out on an M1, and was able to reproduce the issue. It seems like more resources are thrown at windows you're interacting with, which is super interesting. Any ideas as to how to ensure a constant framerate? We're already setting the framerate to 60 fps using glium's control flow.
