New Kwin crash when returning to GUI from Alt-F1

[oshunluvr]

Starting today, I'm noticing a Kwin crash. I was messing about with loadkeys for the TTY and I also installed a new kernel, but reverting to the previous state has changed nothing - kwin still crashes upon returning to F7 from F1.

Here's the dump from the terminal when I restart Kwin:

I'm running the same fully updated Neon you are, with Btrfs and my NVidia is a GT 650M. When I do "Ctl+Alt+F1" I get a terminal. When I do "Ctl+Alt+F7" I get my desktop back. My mouse disables the touchpad again and all seems well in the garden.

PS - I am using sddm.
