A data point from Wayland (https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/xdg-shell/xdg-shell-unstable-v6.xml#n1018): <event name="configure"> <description summary="configure the popup surface"> This event asks the popup surface to configure itself given the configuration. The configured state should not be applied immediately. See xdg_surface.configure for details. The x and y arguments represent the position the popup was placed at given the xdg_positioner rule, relative to the upper left corner of the window geometry of the parent surface. </description> <arg name="x" type="int" summary="x position relative to parent surface window geometry"/> <arg name="y" type="int" summary="y position relative to parent surface window geometry"/> <arg name="width" type="int" summary="window geometry width"/> <arg name="height" type="int" summary="window geometry height"/> </event> So (in their current "unstable" anyway) they are returning the relative placement. And running the risk of sneaky clients probing the display boundaries. I claim this as "prior art" and propose that we do the same by sending a MirRectangle notification. Any objections before the weekend please.
