Probably the plotter again. Do you have a system load viewer plasmoid or something added?

The recent crash was with the network-manager in the panel trying to disconnect a bridge connection from menu of connected devices, the crash before this one I was just clicking on battery in panel all in are system tray widget. there are other before but don't remember what I was doing. for me it is not so frequent, I guess it happens only when multiple mouse clicks reacting with panel or widgets so it crash handling them.

what this say ? what is libQt5Quick responsible for ?
I guess something to do with Rendering backend: OpenGL 3.1 !, It is not disturbing my experience with KDE plasma, just happened 3 or 4 times, KDE is an amazing desktop beast, no problem for me at all.
hope this get fixed next releases of KDE plasma.
