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.

Try using screens with different resolutions at the same time. Always gave me trouble. In my case was always using a horizontal one and a vertical one together. I've had framerate problems, tearing, artefacts (parts of the vertical screen wouldn't update while the other 2 worked fine). From time to time, X will forget my monitor configuration too after a reboot / unplugging the dock / waking from sleep. All that with 2 laptops from different brands using different docstations, one with XFCE on Ubuntu and the other with KDE on Arch. I got it mostly working, but it's still troublesome
That 40 year old X protocol might be the issue here, use wayland for multi monitor with different resolutions.
Yup, I suspect that is indeed the issue. Haven't tried KDE in wayland yet as I've seen some people saying it's still a bit rough. Will give it a try anyway. May give sway another shot too
