I saw this issue once as well and I fear it's a bug in Qt. So far I had not been able to reproduce it at will and especially have not seen it in my Wayland session.
We are soon going to require Qt 5.9. It is very likely that the issue got fixed. If you are still able to reproduce with Qt 5.9 please reopen.
I just encountered this issue once again but I already had it maybe a dozen of time, in my current KDE/Plasma version and in previous version(s ?). My setup: - Kubuntu 17.10 packages - Plasma 5.11.3 - KDE Frameworks: 5.39.0 - Qt 5.9.1 Actually it's the first time I manage to remove this popup without restarting kwin (or plasma, I don't remember). I think this time I just opened a new "Move to desktop" submenu from a dolphin window and the remaining popup disappeared. Here is my "qdbus org.kde.KWin /KWin supportInformation" output: https://paste.ee/p/pj2Yr Good luck kwin heroes !
