Hi there,

I was trying to run plasma on wayland from time to time over the last years. 5.12 (with recent unstable kde-frameworks and Qt5) now looks really great - besides some issues.

1) It seems I can't go fullscreen with kde applications. E.g. F11 in Gwenview just shows the Fullscreen style (dark colors, top bar scrolling in) but it doesn't go fullscreen or even changes window geometry. Also the logout screen doesn't cover the desktop, it shows up with borders, window below panels.
VLC-3.0 with qt5-frontend goes fullscreen just nicely so I assume this is kde-related.

2) systemsettings "mouse" input module crashes systemsettings. This is the output:
Code:
kcm_input: Using X11 backend
X Error of failed request:  BadAtom (invalid Atom parameter)
  Major opcode of failed request:  131 (XInputExtension)
  Minor opcode of failed request:  59 ()
  Atom id in failed request:  0x0
  Serial number of failed request:  23
  Current serial number in output stream:  23

I tried to run it trough gdb, but it ended up with an empty backtrace.

3) Adding a desktop widget ("Plasmoid") crashes plasma:

5) Colorcalibration through displaycal (in Autostart) doesn't work. I need a calibrated monitor for photo editing. Going the kde way and configure calibration in systemsettings just thows a stupid error telling me I should install the calibration file in one of the standard locations - which I obviously did, but still it refuses to see them :/


===

I come here instead of opening a report on bugs.kde.org because I think most issues are obvious if you just try to use the desktop, so this might be an issue with my setup or config or Gentoo ebuilds.
I'm on gcc-6.4.0-r1, but still with 13.0-plasma-profile - I won't be able to update (and re-emerge world) before April. But I don't think the profile should cause these crashes/misbeaviour.

Thx

2) and 3) from my list above (mouse settings and adding plasmoids) seem to be fixed after an update to plasma-5.12.1 and Qt-5.10.1. The other issues still remain.

Is there nobody using plasma on wayland or am I the only one eperiencing these issues?

I briefly tested it after 5.12 release and encountered a crash-happy systemsettings and KDE PIM, other than that had a pretty solid experience compared to earlier runs. However, it is important to be aware of the known Plasma-wayland errata https://community.kde.org/Plasma/5.12_Errata and that this is still a work in progress.

Thx for your answer and the link! So it seems Wayland is not yet a fully functional/stable alternative in KDE/Plasma.
But I have to say that they really made good progress from what I saw from my periodical testing.

The only crasher I've found so far was also in systemsettings5, but in the plasma-nm (networkmanager) settings applet.

When loaded within systemsettings5, the UI doesn't reduce to fit the pane it's in; rather there is a grey extrusion from the right of the window area. It is scrollable but scrolling it to the left pushes the content over the menu sidebar.. It also doesn't update the menu sidebar as the other applets do (it still shows the top-level menu, rather than going to the Network submenu as with other applets). There are similar UI issues when loaded on its own (from plasma-nm settings button), and resizing the window in that instance caused high cpu requiring the applet's process to be killed.

FWIW the mouse module seemed OK. By and large, the overall experience is better than I was expecting :)
