SUMMARY
When using "Detect Window Properties" there seems to be no variation in "Window types" and "Window role". This could be a Wayland issue but previously when I used X it would differentiate between the different windows.

STEPS TO REPRODUCE
1. (this is just one example) open konsole
2. use "detect window properties", set to some size and "apply initially"
3. in konsole open multiple tabs, go to close konsole, popup shows up with "are you sure" type dialog. note it will also be the same size as the main konsole window
4. use "detect window properties" on the popup, "window types" and "window role" don't detect anything.

OBSERVED RESULT
popup is applied the same settings

EXPECTED RESULT
able to differentiate between the different window role/types.

Wayland windows return an empty string for windowRole()

https://invent.kde.org/plasma/kwin/-/blob/master/src/waylandwindow.cpp?ref_type=heads#L118

Is the concept of "window role" completely deprecated on Wayland? 
If so, we should find some alternative property to match different kinds of windows

It's just not a thing.

https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/238 will provide something similar.

Is this (blank text in "Window Types" menu) related?

Comment 4 Dominik Kummer 2025-06-22 02:01:15 UTC

Surface::tag() and Surface::setTag() in conjunction with wl_proxy_get_tag() and wl_proxy_set_tag() are not implemented yet in kwayland/src/client/surface.cpp.

Also Window::windowRole() should probably translate PlasmaShellSurface::role() enum to according QString

Both pieces of info are needed by clientToVariantMap() in kwin/src/dbusinterface.cpp
