      Description

      Based on the commit reference, wl_buffer is attached as NULL to the wl_surface. wl_buffer NULL is not the correct way to use wayland.

      QtWayland::wl_surface::attach(0, 0, 0); is used to hide the surface. NULL surface is not valid as per wayland,

      Even though the document says
      >>If wl_surface.attach is sent with a NULL wl_buffer, the following wl_surface.commit will remove the surface content.

      But causes unexpected behaviour that depends on compositor. xdg_surface will throw error and weston will get stuck.
