OS: Arch Linux, sway with xwayland
Terminal: Foot

Xwayland is pretty heavy service, even if it auto terminates, it consumes 141MB for few seconds

So you use sway with still enabled xwayland and no pure wayland session only.
Currently I would assume, that this is something wl-clipboard respective wl-copy & wl-paste do by their own to support pasting into X windows depending on the current wayland session.

But I could be wrong.
Can you try if the same happens when you invoke wl-copy or wl-paste from your terminal (Foot)?

[Kacper-Kondracki]

Nope, invoking wl-copy or wl-paste doesn't launch xwayland.
After investigating further I see that micro uses clipper for clipboard which is made by the same author. It's bug in clipper.

Clipper should just launch wl-copy/wl-paste. I don’t have a wayland environment to test in, so if you discover how the issue might be fixed please let me know.

After further investigation, I figured out that the issue happens with wl-clipboard when piping text to it
echo "Hello" | wl-copy
But wl-copy Hello doesn't launch xwayland. From clipper code I see it is using wl-copy stdin.

I'm opening issue in the wl-clipboard repo
