I also can't reproduce in 5.11.5, Frameworks 5.41, and Qt 5.9.1.

For anyone who is still hitting this with recent versions of things, can you
list them here? Thanks!

Well I spook too soon. The rule wasn't saved (I probably didn't click on
"apply" even if I thought I had). So with the rule "show desktop" seem to work
properly.

Sorry for the delay (but I'm officially no longer here ;-)

run "kcmshell5 kwinrules", "detect", click the desktop, ensure to select *all*
window types in the lower listview of the main dialog and finally in its
"appearance and fixes" tab, force the window to be of desktop type.

According to the latest dupe, this isn't limited to desktop showing but the
type juggling also occurs when simply clicking the desktop when as a result the
desktop eg. moves above keep below windows.

@Jeremy, as a workaround create a kwin rule (this oc. requires you to use kwin
as WM ;-) to enforce the desktop to be of desktop type.

Ensure to match normal and "unmanged" windows as well to have the rule applied.

Plasma can then fight with QtQuick on juggling the type as much as it wants,
KWin simply won't look there anymore.

I confirm too that with plasma 5.5.4 the problem is still here. The "show

--- Comment #48 from Marco Martin  ---
there is an ensureWindowType() in DesktopView that seems a bit too happy about
re setting the type on a lot of kinds of events, so yeah, that has to be
redesigned a bit

is it safe (and fast enough) checking what the existing window type is fairly
often?

(In reply to Marco Martin from comment #48)

I beg your pardon??

The KWindowSystem classes operate on locally cached data, so the X property
isn't read on queries, but when it changes. The check is always "safe".

Why do you think you need to "ensureWindowType()"?
Nothing but the client (plasmashell) should ever change the type anyway.

Indeed, it actually "should" (only) be set for an unmapped (before
showing/managing) window - KWin is a bit graceful to respect runtime changes
here (likely because the spec says "should" - and once more it's no way clear
what the expected behavior is itr)

=> The "correct" behavior is to set the type before showing the screen and then
"expecting" it to remain untouched. If "something else™" touches *your*
property, "something else™" is maicious or broken.

--- Comment #51 from Marco Martin  ---
because the whole api of that class was done around that yeah, was fine to
change window type at runtime. since it turned out it isn't, the dashboard
thing was removed, still a lot of untangling has to be done.
probably it should be able to set the window type only before a window show?

in theory yes, in practice: well Qt might mess with it

Unless Qt screws something (implicitly, by generating a new drawable?) you
should only have to set the window type *once*.
Unfortunately, Qt::WA_X11NetWmWindowTypeDesktop is only available for QWidget
(and I assume it's not?)

Is there any bugreport on the type being altered unwantedly or can we assume
that this is just a leftover from the desktop -> dashboard approach?

AFAIK it's anyway ignored in the xcb platform.

Ok, did "xprop -spy _NET_WM_WINDOW_TYPE" on the plasmashell desktop window and
it changes like hell on desktop showing, most of the time from
_NET_WM_WINDOW_TYPE_DESKTOP to _NET_WM_WINDOW_TYPE_DESKTOP (why does it
"update" its type property???) and sometimes it turnes into
"_KDE_NET_WM_WINDOW_TYPE_OVERRIDE, _NET_WM_WINDOW_TYPE_NORMAL", so when the
layer update looks "at a bad time", it's not a desktop.

This is clearly a bug in plasmashell, re-assigning.
