I was not sure if you were still running that setup.
Anyways if opensuse works it only can be either kernel or xserver. If you have both on the same version as on opensuse it should behave the same way. That's for the crashes at least.
The rest sounds like being a consequence of kwin crashing. Like losing its settings and such.
