It seems to be a kernel default to use 16bpp by default. By using
"cirrus.bpp=24"
as kernel option, kwin_x11 works fine.

That sounds like a bit too much, everything except cirrus with 16bpp seems to
work.

For master I'd be fine with that as well. Cirrus is a weird device/driver combo
to work with and there's work ongoing to switch to -vga std in openQA by
default.
(at least three years too late, if you ask me).
