> Last thing, with single buffer, I would expect tearing more than stuttering,
It's a race between the Wayland server reading from the buffer and Xwayland
drawing to it. This can result in tearing if those two operations can actually
run concurrently, which is the case with amdgpu, but not yet with most other
drivers AFAIK.
Either way, it can result in the Wayland server already displaying a client
frame too early sometimes, hence the stuttering.
