I can confirm this issue as Wayland specific.
> A temporary solution I've found is to reset Plasma
Yes. In my testings, killing plasmashell process and starting it again
mitigates this bug. And not "until it happens next time", but until log out.
So, there's something going on when plasmashell starts for the first time
during Wayland session. Error messages on console are the same, but restarts
are not glitched somehow.
Jul 21 16:04:51 orange plasmashell[49983]: qt.qpa.wayland: Wayland does not
support QWindow::requestActivate()
Jul 21 16:04:52 orange plasmashell[49983]: kf.plasma.quick: Couldn't create
KWindowShadow for PlasmaQuick::Dialog_QML_24(0x557d0d675a30,
name="popupWindow")

KWindowShadow for PlasmaQuick::Dialog_QML_24(0x557d0d675a30,
name="popupWindow")
Jul 21 16:04:52 orange plasmashell[49983]: kf.plasma.quick: Couldn't create
KWindowShadow for PlasmaQuick::Dialog_QML_24(0x557d0d675a30,
name="popupWindow")
I got logs of non-restarted plasmashell from journalctl, of course.
Even after applets start disappearing, there's still a chance that they will
appear after any next click.
Plasma tooltips stop showing up randomly, and they seem to be unrelated to this
bug. At least I haven't found any consistent pattern.
Applets placed on a desktop are also affected by this glitch.
Some times after interacting with Plasma panels and widgets for a while, it may
stop responding (and KWin shades it with light gray). It may unfreeze though.
It is NOT eating any noticable amount of CPU when it hangs like that. Once I
attached gdb to a frozen Plasma, detached, and it unfroze. Might be unrelated
though. Backtrace of frozen plasma (missing some symbols, I know):
