Great to see that Wayland is working very well with KDE now!
On the minus side, I've just bought a Logitech MX Master 3S mouse
(expensive but I *love* it!), which works marvellously on X11 but is
quite laggy under Wayland. The screen pointer frequently stops while
the mouse is moving. Is there a setting that would fix this?
As for the plus, the first one is that seemed to be the only obvious
reason not to stick with Wayland.
Secondly, I tried Wayland because I was getting a failure on X11 with a
webkit based program. It gave me an excuse to (re)try Wayland, and IT
WORKED!
While that was marvellous, it made me wonder if there was anything I
could do to get it working under X11. The error messages were
KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied

I found various reports of this on the interweb, mostly suggesting that
it was to do with NVidia drivers (I have an NVidia Geforce GT 710
card), but clearly I've got a functioning version because Wayland found
it. Is there any way to get X11 to use the same driver?
My system is using akmod-nvidia-470xx version 470.223.02.
It does have a later version, 550.54.14, but this is "only" akmod-
nvidia", suggesting it's not specific for my card?I have
I have two boxes running kde and X11 in F38 with nVidia GT 710 cards and
rpmfusion 470xx drivers. They worked well until a few weeks ago when
one box started reporting graphics resets in Kwin, which I posted about
here. I'm still seeing them, usually with a quick autorecovery. I
haven't yet tried nouveau.
But it has been my understanding that 470xx doesn't fully support
Wayland. Today I tried a Wayland login, but was consistently returned
to the login screen. X11 is still mainly ok. I'm wondering why Wayland
is working for you.
