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.

I have the same experience. I wrote a simple program with SDL2 to test a software renderer. All it does is create a window then go into an event loop and after each iteration it streams a framebuffer to a texture that gets displayed in the window. In the default mode (X11) my frame timings fluctuate a lot and for a while I tried to massage the code to get it stable because I was convinced that it was just my draw code. Then I eventually forced SDL2 to use Wayland and not only did the draw time per frame go down by 2ms but the fluctuations went away completely.
