When switching windows with ALT+TAB, Kwin sometimes crashes (every 5-10 mins)


STEPS TO REPRODUCE
1. Hit ALT+TAB

I'm afraid we need a stack trace if there was a crash. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl
