OK, your answer seems aligned to Mike's one. So, another question: when we iconify a window, it should still appear in the "toplevel" list of windows, e.g. for ALT+Tab. Does the same happen when we hide/withdrawn a window? Would be good to have a clear difference between iconify, withdrawn and hide. So far, withdrawn and hide are being treated exactly the same in Wayland engines, while iconify will be different (it's a server-side thing, the client won't free any resources at all). > We also need to sort out (higher level, not in the engine) all of the > withdrawn true/false settings on hide and show and decide what can and > should be done in many cases.
