--- Comment #20 from Szőts Ákos <szots...@gmail.com> ---
During the day kwin was running in Valgrind and it crashed seven times and
produced 19 different Valgrind .log files. I tried my best to de-duplicate the
error and leak messages there (there were many repeating).
Here come the errors from Valgrind:
