It's my personal top candidates in the order of my preference (best to worst) from my notes when I was researching this topic for my parents. (funnily enough, they ultimately settled on kdenlive, despite not being very computer proficient, because they found more step by step yt guides for what they wanted to do with it)
All still actively maintained.
I played around with each of those for a bit some time ago and they were quite similar, so you can pick by your personal preference.
Interesting discussion, the opinions go both ways but the official ones seem to disregard some facts and base the decision on some arbitrary ones that were not listed in OPs linked article, which I find quite biased or at least untransparent.
to me that smells like what I said in the other comment:
Wayland might be a bit stricter when it comes to following specs and not implementing hacky workarounds. (or it could always be a bug)
I feel like, if a cable is high quality and up to spec, it will work with wayland. But if the signal integrity is below spec, wayland might fall back to slower signaling while x11 is more lax and ignores the issue and so a worse cable still works even if unnoticably below spec quality. Or the 4k over hdmi 1.3 is some hack that x11 supports and wayland doesn't because it's out of spec.
it's probably a file on the disk somewhere so try using the
findcommand on / and filter name by *.icc extension. You should spot it from there.
