KDE requires that buy-in into the rest of the software that comes with it. Otherwise, I don't think it offers that much more.

Not that it is the desktop environment that I install on hardware when Sway is not an option.

it's a shame it didn't live up to the hype for you, but I'm hopeful that the Plasma team will take the feedback constructively -- none of the issues you pointed out are the sort of thing that requires a huge rewrite, so I can absolutely see all of them getting fixed in future versions!

I honestly had a similar experience to you back when I used Plasma -- I constantly found myself getting frustrated by small glitches and stutters (and a few bigger bugs like one where connecting a second monitor would completely reset my desktop layout and delete all my panels and widgets), until I eventually switched to Gnome (I need 500 extensions to be happy but at least I am happy).

Maybe you want to have a look at the option:

"Window Management" -> "Window Behaviour" -> "Advanced" -> "Window placement"

I have set it to "Minimal Overlapping" and it's the main reason why I never even considered using a tiling window manager. My konsole windows (I like them statically at 80x25, as nature intended! 😉 ) line up just as I like it and everything else is placed fine when using the "drop it to the edge" feature. But that's my personal preference, of course.

@Linux_Is_Best He is approaching it in his own way and makes entertaining videos along the way. Nothing to worry about if you ask me.

Much more interesting than all those boring superficial demonstrations on perfect fresh installs that are already out there on video.
