--- Comment #16 from Oded Arbel <o...@geek.co.il> ---
I also experience frequent (daily) kwin_wayland complete freezes - though I'm
unsure if it is related to this bug:
- I don't believe it is related to task switcher or overview (I frankly almost
never use either)
- when kwin freezes, the main seat is completely dead - I can't even switch to
a VT. I can only recover by SSHing to my machine and issuing kill -9.
I'm running Neon testing - up to date as of today - but the issue has been
happening since RC1 dropped. I managed to get a thread dump of the frozen kwin,
and I can see that the main thread (that pegs the CPU) is running this:
