Well, if a toolkit wants to render the same GUI on outputs of differents properties (those properties significant for actual rendering), they will have to render several times, no other choice to do things properly.
The other option would be to ignore those output properties, and the compositor would manage something with an output agnostic buffer. In that case, we would remove the subpixel property from the output to stay consistent (mode is used for shell surface fullscreen). Your proposal is middle ground: a set of buffers, and some heuristics applied on their properties to combine those in the compositor space. For simplicity, I dare to think one buffer for one output is quite clear cut and easier to deal with. Of course, there is also the brutal way: output becomes a singleton, keeps its properties to let the toolkit render "properly" (hopefully that would be significant), namely we would drop support of several outputs. -- Sylvain _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-devel
