> think the main (or only? not sure) culprit is Firefox (running natively on Wayland) https://bugzilla.mozilla.org/show_bug.cgi?id=1726360 - it reports to be fixed in Firefox 93 but I'm on Firefox 92 still, I guess I should just update.

I was just about to write the same, the only clipboard issues I've had in wayland were with firefox. I don't know what they do, but even in windows I get weird behavior at times (e.g. when copying out of Jupyter cells for example), much less than wayland though.
