Wayland support in KDE is improving as we speak. Two recent improvements:

* https://bugs.kde.org/show_bug.cgi?id=373907#c29

My experience is totally the opposite. In fact, at work we are now migrating many of our computers from GNOME to KDE because we are really tired of GNOME's bugs (and it's "too simple to the point of being useless" interface).

The grass is always greener!

I can assure you that there are plenty of bugs on both sides :)

Indeed there are. We use CentOS, I have been testing CentOS 8 for several months without problems, and suddenly the numpad and special keys like Alt stopped working for KDE programs. Why? I don't know :/

I don't really have problems with multi monitor and KDE.

Same here, running a pair of 1440p monitors off my Hades Canyon NUC, running Kubuntu 20.04.

Largely now without tweaks, but it needed some when I originally got it to use Kisak-mesa.

neofetch output: OS: Ubuntu 20.04 LTS x86_64 Host: NUC8i7HVK (REMOVED) Kernel: 5.4.0-42-generic Uptime: 5 hours, 7 mins Packages: 3266 (dpkg), 7 (snap) Shell: bash 5.0.17 Resolution: 2560x1440, 2560x1440 DE: Plasma WM: KWin Theme: Breeze [Plasma], Breeze [GTK2/3] Icons: breeze [Plasma], breeze [GTK2/3] Terminal: konsole CPU: Intel i7-8809G (8) @ 4.200GHz GPU: AMD ATI Radeon RX Vega M GH GPU: Intel HD Graphics 630 Memory: 8898MiB / 32031MiB

I do - every time I unlock my screen, Plasma crashes, and my windows get randomly distributed around my virtual desktops.

Oddly enough, if I only have one monitor enabled, it doesn't happen. And yes, I've nuked my preferences several times.

I have the same problem consistently on PopOS which uses GNOME just across two monitors. As a bonus, in the redistribution process, windows are randomly resized to a lot larger sizes. I suspect this is related to me leveraging the experimental scaling features in GNOME which is hard to avoid using 27inch 4K monitors. Really wish the window management would be more polished but I have no skill in that domain to make it better.

I'm running three screens and don't have the same problem. I did a clean format before installing KDE, though, just because that computer had been upgraded from one version to another for around ten years.

Are you using Wayland? If so, try X11.

Multi-monitor works well for me but I have one annoying issue which is that one line of pixels bleeds over the edge of one monitor into the next.

Nor do I.

I would even venture to say that, as I discovered last month with several Debian setups, it is the best multi-monitor plug'n'play experience I have had so far.

I believe the preferred environment for KDE is one in which you are liable to have the most recent libraries including bug fixes which sadly has often not been the case for people using kde + ubuntu.

I can't speak to Wayland support, but almost all the bugs I've seen with plasma appear to be GPU specific. My laptop with Intel graphics runs KDE rock solid, while my desktops with Nvidia cards have all sorts of issues, and nouveau had different issues compared to the binary drivers.

At least their apps are pretty DE agnostic. I use them on Cinnamon mainly and sometimes Windows.

I stopped using Ubuntu 10 years ago, because I couldn't stand how buggy it was, but later I realized it was mostly GNOME. It's interesting how things turned around.

Edit: looking at other responses it seems that this still holds true, perhaps it's just Wayland support that's buggy, because it is new.

> especially when it comes to multi-monitoring,

It's getting better on the multi monitor front at least
