Happy to hear it's already fixed though. Now to get Ubuntu to merge the fix... it's "fixed" by replacing switcher - ubuntu will unlikey backport that to 4.8 |
Created attachment 69827 [details] backtrace I have a hot key set up to traverse desktops. When I press it repeatedly in a fast manner, I sometimes trigger a crash in kwin. I can repeat this 3-4 times a day.
