I think i have the same problem. Kwin hangs when i trigger desktop grid
(arbeitsflächen-umschalter (Raster)) via the screen edge. This only happens
every few days.
I noticed this problem on my workstation with the nvidia blob but also on my
laptop with intel graphics.
On the workstation i used opensuse Leap 42.3 (kwin 5.8.7) and now tumbleweed
(kwin 5.11.2) and on the laptop arch (kwin 5.11.2), so there is hardly a
pattern.
However, i _think_ the problem only occurs when kdevelop is running on the
current desktop. Its a little hard to tell, because its always running on my
workstation and i dont use the laptop that much.
My backtrace from the workstation with kwin 5.11.2:
