New crash information added by DrKonqi
DrKonqi auto-attaching complete backtrace.
The backtrace looks to be entirely in Qt.

Since then, it shows the splash screen, then goes back to the desktop with no wallpaper or panels and no messages in stdout or stderr. Being in qsgthreadedrenderloop makes me wonder if you've perchance changed the render loop setting at all. Have you? You can check by searching for "renderer" anywhere and opening the "Plasma Renderer" item that appear. Let us know the value of "Rendering loop" in the window that opens.

Both drop does are on automatic and the checkbox is unchecked. |
