I can reproduce this on git-master. Try (workaround to make it work): QT_QPA_PLATFORM=xcb plasmoidviewer --applet org.kde.plasma.digitalclock I believe its the same bug I reported https://bugs.kde.org/show_bug.cgi?id=506106 *** This bug has been marked as a duplicate of bug 506106 *** I don't believe this is a duplicate of bug 506106, unless where it fails is just inconsistent.

Patch to test for KWindowEffects::Effect::Slide
Thanks for looking into this. I agree this is not a duplicate of bug 506106. My fix however fixing both. My backtrace shows an additional Wayland geometry re-entrancy in PlasmaQuick::PopupPlasmaWindowPrivate::updatePositionWayland(): calling QWindow::setPosition() triggers a GeometryChange event that routes back into updatePosition*(), causing a recursion and SIGSEGV. Patch attached (against plasma-framework / PlasmaQuick, not plasma-sdk). Created attachment 184435 [details]
