plasma has wayland support, tons of customizability, better multi monitor support, a great suite of applications including a text editor with lsp support and much more, and in general looks nicer. cinnamon is sort of the bare minimum
better multi monitor support
I run a 3x1 setup and KDE didn’t handle it any better than Cinnamon did.
Wayland support is coming to Mint. You can actually use it on 21.3 right now but it is unstable.
Rest of what you said is opinion.
Wayland has objectively better multi monitor support in every case. You were encountering tearing issues before switching, maybe you just didn’t notice.
Well, I got rid of KDE and I’m on Cinnamon right now, so where are these tearing issues? You think I would have noticed after over a year of use.
the rest also isn’t just an opinion, cinnamon does not have an equivalent to kdenlive, krita, or kate. even the existing applications are just not on the same level. it’s an acceptable desktop, but plasma and gnome are just better.
Does that include support for variable refresh rate with multiple monitor (Freesync in my case).
