Hi pq, I was thinking of a more full-featured example using sub surfaces with runtime positioning and z-order control.
That aside I am having an interesting problem. In case of multiple surfaces, I only see the frame event for the last added surface. Surface A is behind B and C (tiled), none occluded. Here I get a frame callback for B. I'm using the commit pattern from B to Base. Surface B Surface A Base Adding sub surface C, with registered callbacks for B and C, I only see a frame callback for C. I'm using the commit pattern from C to Base. Surface C Surface B Surface A Base I don't touch the B callback when the C callback is added. Does anything stand out? Thanks, Joel
