Xwayland being hardware agnostic, if Xwayland was the problem, I'd expect t=
he
issue to occur with any hardware., and yet I don't see this on intel for
example.

Lyude, you mention this is with drm-tip, can you confirm if this started wi=
th
the DRM update or does it occur with the current stable code as well?

Last thing, with single buffer, I would expect tearing more than stuttering,
from the screencast, it looks like it's flipping to a back buffer which was=
n't
updated in time.
