Plasma & Wayland & mixed DPI - I want to, but it does not

After every update of my Fedora 34 that touches something related to kframework o plasma I try wayland on my machine again. I want it to happen, the promise of having 100% on my FullHD laptop screen aside 115% on my 4K screen is just to good to be true. On top, font and icon rendering on Wayland is way more crispy, I just want it to be good!

But...

strange things happen:

- Copy'n'paste works in 50% of cases. I am a programmer and without copying code from stackoverflow.com I am fxxxed :D Seriously, it is really annoying in coding sessions (vscode & Jetbrains IDEs)

- No screen sharing in Microsoft Teams (yeah, I have to use it) but also not in Zoom. There is a slight improvement when using Teams as a web site in chrome (or as PWA on the desktop), it let's me share some (?) app windows, but choosing to share one of the two screens entirely, the screen is sent as black

- Libreoffice scaling is totally broken. Unusable huge icons on the FullHD screen, unusable tiny icons on the 4K screen. Actually, it should be just reversed. Additionally, display glitches. The cursor is rendered at wrong positions, popup menus and tooltips are placed totally wrong, like 50% off horizontally, acutes not working (I type spanish a lot)

- quite similar to Libreoffice: Virt-viewer and remmina. Performance of SPICE sessions is generally sluggy

- Plasma itself is somehow okay-ish.

- Tooltips and menus are fighting for focus, finally ending the fight when the mouse cursor moves over closing both. annoying. happens on panels, system tray, app launcher.

- the panel starts in a random configuration on every logon. looks like reincarnations of some panels I configured before, butt vanished when using a X11 session

Too sad that it is still not usable for me. I really want it to happen!
