On Wayland, the second time I open the popup for Kickoff, the System Tray, the digital clock, or anything else with a popup, I get this logspam output kf.plasma.quick: Couldn't create KWindowShadow for PlasmaQuick::Dialog_QML_230(0x35d4e80, name="popupWindow") kf.plasma.quick: Couldn't create KWindowShadow for PlasmaQuick::Dialog_QML_230(0x35d4e80, name="popupWindow") kf.plasma.quick: Couldn't create KWindowShadow for PlasmaQuick::Dialog_QML_230(0x35d4e80, name="popupWindow")
This is because the showEvent is delivered to dialog before there is a wayland surface/platformwindow notified, but updateTheme() and friends already trigger creation of the shadows
No longer an issue today.
