Yes it does, but that drawing is done for X11 (xcb) - I mean, that
Cairo drawing goes to a X11 Window directly, which then comes back from
Xwayland server for final composition, if I read
weston_wm_window_create_frame() right. It has a call to
cairo_xcb_surface_create_with_xrender_format().

It could not use local buffers unless we changed how the XWM works wrt.
X11 decors.


Thanks,
