120Hz refresh rate is listed as an option on some laptops that are really only 60Hz.
This screenshot shows it happening in a Xorg session. It looks like the correct frequencies 60.01 and 59.97 are being accidentally doubled.
I can't remember if I've seen the problem occur in Wayland sessions too. But it has appeared on a few different laptops that are definitely only 60Hz.
