Will that make it more usable for nvidia users? I hope to someday try SteamOS with nvidia but I think most of the wayland issues are what's preventing that.

The task bar, for example, will often stop being useable and freeze up. I have had the digital clock widget freeze up on me, which requires a relog to fix.

Thankfully this has been tracked down, and will be fixed for Plasma 6. If you run into it, you can hit Alt+F2 and run kwin_wayland --replace which will restart the shell.

If you go into edit mode, and edit the task bar widget that shows your running applications, disable the option that shows window previews upon hovering over the application. Apparently that is the thing that causes the renderer to fail on non Intel GPU systems. Here's the bug report that goes over the whole history if you're interested.

Definitely feel you on the overall Nvidia Wayland KDE issues. I really wish I was in a position to be able to pickup an AMD GPU.

There's still weird bugs with Plasma Wayland unrelated to GPUs too. For whatever reason, dragging a file from a notification (e.g. Spectacle when a screenshot is saved) to Discord will make the shell just quit and restart...

Well, they're both pretty good.

Xfce starts off closer to the way I like things and requires less messing around with the config to get it all the way there. It changes less frequently, which I appreciate. It uses slightly less memory, seems to go wrong less often, and has fewer things I have no interest in like 'kwallet' or whatever. And I appreciate what seems to me its more approachably modular nature (which I've used only for a couple of minor things.)

for me, simplicity.
