From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Thanks for the detailed answers. So we can say that Wayland sacrifices lower latency in exchange for higher accuracy.
According to this post Gnome allows you to change this behavior through an environment variable (
MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0
on Ubuntu 22.04). It should be a configurable option, considering the amount of people complaining about this mouse behavior.Sad, but does this problem only affect Wayland or also Xorg?
Note that depending on compositor switching to the legacy API might not help due to how they are designed. And with legacy you'll also probably lose the fancy modern crap like HDR. A workaround I did in my own not-public fork of sway is to use the legacy API for cursor stuff and atomic for everything else. Seems to work well enough in getting the best of both worlds.
Wayland compositors only in my experience.
