--- Comment #2 from Rainer Finke <[email protected]> --- I've tried to get a backtrace (connected via SSH and gdb to kwin_wayland), but kwin seems to exit directly after pressing Alt + Tab. I've compiled kwin-git, to have on Arch Linux a debug output available, but it didn't change anything. I've tested it now as well on a Intel GPU, same issue. After Alt + Tab, you cannot do anything anymore on the machine as the system freezes and doesn't accept input anymore (except SSH and reboot). (gdb) continue Continuing.
