Ondrej,
You need to install Kwin Wayland and another package that will provide the backend.
My experience wasn't the best, several apps crashed, effects stuttered or were very slow, even typing felt slower. But at least my desktop looked normal.
One comment: the logging out issue is not because of Wayland. I have the same with Xorg, and there are several bug reports pointing to the same issue.
Kind regards,
Lailah

So yesterday I tried to log in to the KDE Plasma + Wayland session on
my laptop (F32) and the experience was unfortunately quite horrible...
1. When I logged out of the X session, switched to Wayland on the
login screen, and logged in, I only got a black screen. After I
rebooted, I managed to login to the Wayland session (I have automatic
login after boot enabled), but...
2. The desktop was all squeezed into a small 1024x786 rectangle in the
upper left corner of the screen (my screen is 1920x1080). So I opened
system settings to change the resolution, but...
3. The screen settings were showing "manufacturer_TODO" and
"model_TODO" as the name of the screen and the only resolution offered
was 1024x786.
4. The window layout of my KDE session was not preserved (I think even
the distribution of windows to activities was lost). But I probably
shouldn't expect this to work...
5. Logging out of the Wayland session gave me just a black screen with
blinking cursor, no login screen.
Reading the other posts in this thread it seems I'm the only one
experiencing such serious breakage (maybe except 4., which is
understandable), so I'm wondering if I did something wrong... I simply
installed plasma-workspace-wayland, logged out, and then logged in
selecting "Plasma (Wayland) (Wayland)" from the session dropdown.
