multiple wl surfaces commit in one client

Hi pekka I want to ask if in one client have created many wl surfaces, and commit all of them to weston in one frame, could weston guarantee to handle these surface update commands in one repaint? The sample code may like this: redraw() { wl_surface_commit(surface1); wl_surface_commit(surface2);

hotplug in weston

Hi all, I want to ask if hotplug is fully supported in weston 8.0? I see some related hotplug changes in drm-backend and compositor, but how to handle windows if there is application running on that output plugged out? Is desktop shell or ivi-shell support hotplug? Thank you! Best regards Nancy

Hi Daniel & all I find the function drm_output_prepare_overlay_view() only use the plane type of WDRM_PLANE_TYPE_OVERLAY. it could be a waste for some planes of type WDRM_PLANE_TYPE_PRIMARY if the universal planes is enable. For example, the kernel define 6 crtcs, and each crtc will have one pri
