And here's why freedesktop.org is broken as a standard body: "This is no longer supported in gnome-power-manager. This spec is considered obsolete."
Welcome to freedesktop.org. freedesktop.org is open source / open discussion software projects working on interoperability and shared technology for X Window System desktops. The most famous X desktops are GNOME and KDE, but developers working on any Linux/UNIX GUI technology are welcome to ...

New bug reporting workflow:
" Please try switching to modesettings xorg driver."
Reply: "Indeed, that is fixed with modesetting. It also seems to solve another problem I had. Thanks for the input :)"

It's unbelievable how many issues get fixed by just kicking out that Intel driver. I see it myself on one of my systems. On Wayland everything is fine, but when starting on X the rendering is just completely broken due to not yet using modesettings there.

Is there a notable performance difference between modesetting and a GPU-specific driver using glamor? Because the radeon X driver already uses glamor for at least Radeon Southern Islands (7000) and later.

Lately we start to get more bug reports for Wayland. Which is great and also highlights very well which window management features I don't use. Minimizing doesn't work? Well of course, I don't use that...

Having support for GTK+ on Wayland makes testing easier. Is it bug in KWin or Qt? Let's test how GTK+ behaves, ah correct -> bug in Qt.

Just investigated something weird. Noticed that on a kubuntu system the system looked wrong, but breeze was configured. Looking at the env showed that QT_QPA_PLATFORMTHEME was set which destroyed our integration completely. Further investigation showed that something installed appmenu-qt5 which adjusted the env to set that variable. So if a user has that package installed plasma is broken
