I have Kile inside my default toolbox (Fedora). Everything seems perfect save for this message after launching it (just typing kile in the terminal):
qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x563fb8114340) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x563fb928e640) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents.
I don´t understand very well what is not allowed here…
