Oh hey, it’s 
GNOME with Arc Menu and Dash to Panel.

The Cube you will only draw with four virtual desktops.
Might be a triangle and the penta-gon with 3 or 5 as well.
Also the desktop effect must be activated, it’s not there by default.

Yes, I am one of those with a lot of customization. I use a LOT of configurable window buttons for example. I assume a lot of my problems are due to that and those buttons will need to be modded to KDE 6. I also use xrandr, which does not work in Wayland. But I need it to configure gamma on my dual monitor setup.
I’m planning to set up x11 as a default in Manjaro for some time. Using wayland and there are some issues on both Nvidia and non Nvidia cards

Like what?
From the samplings here it seemed some folks experienced more bugs on x11, but I may be conflating that with ‘missing features’ such as the recording option in spectacle (that requires wayland).
I ask out of genuine curiosity … I had been using x11 until this release.
If you’re interested, you can read the issues I’ve had with nvidia/wayland/Plasma6 - https://forum.manjaro.org/t/kde-megarelease-6-plasma-6-is-here/157389/101
That said, besides the browsers thing, everything else seems alright but I don’t use the Wayland session much since the flickering/tearing in the browsers is often unbearable.
I’m getting weird issues with windows geometry from time to time using different cards so assume it’s not GPU-related
And for nvidia there’s this
I may confirm the issue mentioned in your post
I’ve also tested with no problems opening *.webp files via Dolphin on the most recent fedora 40 KDE nightly build and on openSUSE Tumbleweed with sudo zypper dup as of today (03/23/24). CachyOS 2024.3 (with sudo pacman -Syu also as of today) showed up failure to open via Dolphin *.webp images.
Is what I just saw I accidentally installed (with their screenshotter with pamac) and I now have 4 Gnome login options. Bad idea to keep it next to Plasma?
There is absolute no reason to be sorry for using Plasma 6.
Of course if you are relying on third-party extensions - then you will be sorry - otherwise not.
I have been testing Plasma 6 since many moons - earlier than the official release - quite pleasant in my opinion.

But if its only affecting you I might think its configuration related.
To be fair, I have no idea if you included testing vanilla configs or not.
Just its the only report of that I know about.
Flickering with xwayland on nvidia does seem to be a thing.
(and makes me wonder also if @ydar tried making sure to run the browsers in native wayland?)
I’ve seen absolutely no issues with vsync on either xwayland or natively, with Firefox …? In fact, since switching to Wayland several months ago, all has been fine and certainly far better than an Xorg session? 
No NVIDIA here, in my case, though?
It’s reproducible under some very specific circumstances and actually minor.
And that’s pretty much the reason I don’t want to enable wayland by default for everyone. Also some remote desktop software doesn’t support Wayland (e.g. AnyDesk). I don’t really think it’s a good idea to break these kind of things.
How about ssh -X? I guess similar? I haven’t yet tried that one with Wayland.
Please install the qt6-imageformats package.
- webp :
qt5-imageformats→qt6-imageformats - gimp :
kimageformats5→kimageformats
Thank you very much. It fixes the problem.
Thanks. No I didn’t know about about the option to run it in native Wayland.
So I found over here: KDE 6 - Wayland broken Chrome/Vivaldi - #10 by warcayac - Help - KDE Discuss, the solution.
However, Konqueror still crashes on Wayland, and I haven’t gone further investigating other potential bugs on Wayland. I think for now I’ll stay a little bit longer using X11 since everything works for me there without poking around to manually change configurations.

Sadly the chromium situation is a bit fubared for me because vaapi works now on wayland … but is broken for amd. There is a patch available for chromium so that you can get hw-accel from vaapi in chromium again … but it only works for x11/xwayland.

I don’t know about shortomings of dependecies, but I have tried KDE 6 with EndeavourOS, and I finally can actually use Wayland with KDE on my set up (AMD iGPU(CPU) + Nvidia dGPU + HDMI port bound to nv)
On KDE 5 it didn’t work, and on Gnome it works.
So KDE 6 is a must for me.
Waiting till it be available in Manjaro. Any idea when it would be?

It is …
Stable snap - I don’t know - but it is in testing 6.0.2-3 - and of course - edge branch (unstable)
