    I'm keen to try gaming on Wayland people say it manages vsync off and tearfree/VRR better than X11.. There are also some bugs or unreleased features though which seem to frustrate some. And theres the slight performance loss which seems to be the most important thing

      Just tried it with plasma 5.18 and it definitely isn't ready. SDDM menu item that says (Wayland Wayland Wayland), applications which don't scroll properly, gigantic mouse pointer which comes and goes, missing menu icons in windows that are replaced by a generic Wayland symbol, copy and paste doesn't work... and that was just a quick 15 minute try out.

        Plasma 5.18 is too old. In Plasma 5.19 all problems that you described is gone!

          Will it support NVIDIA without xwayland acceleration and reverse prime?

            Can anyone confirm, that Plasma-Wayland works with proprietary NVIDIA drivers?

              This is so outdated, Redhat, Canonical, Amazon, Intel, Microsoft, SuSe etc, etc are all throwing thousands of dollars into developing linux.

                I am seeing all these comments about how plasma wayland is working fine now, but in my case (archlinux plasma 5.19.5, gpu 7750hd with amdgpu driver) plasmashell crashes immediately after I login in Wayland session. I open terminal and do `plasmashell --replace` then it starts for a moment and crashes again after a few seconds. It was working "fine" (with all its bugs) in the first days of plasma 5.19 when I had tried it. I don't have time to debug it now but a completely non functional desktop is the worst thing that can happen to a user, because you don't even have menu to logout and login with X11 again if you don't know terminal usage (and don't know about krunner which was taking 2-3 minutes to appear after 'alt+F2' in my case). So definitely plasma wayland isn't ready, hopefully it will be for Fedora 34 (probably version 5.21 by then).

But it is just unusable on notebook with PRIME - I could not basically offload anything. And that's on Manjaro. Maybe need to try Fedora since people are using GNOME on Wayland and maybe PRIME works there. So X11 for me now.
                  I was able to play Warhammer 2 on my AMD GPU, while running the display, desktop and a few other applications off the Intel iGPU (thanks to Feral providing a selection dropdown for Vulkan driver). It Just Worked(TM).

                    GDM will actually launch Plasma Wayland and work fine with it. I ditched SDDM long ago, they clearly don't care about Wayland support, or heck SDDM itself.

                      Yeah, that's because the compositor now has full control, instead of having to interject with X server and request it to do things. That means proper control of window decoration, "perfect frames" and other good stuff. Also because the way Wayland is designed, the application just hands off frames to the compositor, and it can do this at whatever rate it desires, so that's why there are no more tearing problems and awkwardness.

                      It's also why VRR is something that the compositor has to work on, because it's the one talking to the display drivers and hardware. Applications using Wayland are already rendering at a variable refresh rate, so it's just that the compositor has to enable VRR on the display and then figure out how compositing windows will work in such a situation.
