Then you want to probably use process to process buffer sharing (e.g. like a nested wayland compositor), and maybe subsurfaces. Then you have a main process that acts as a gateway for other processes and their buffers and input etc. and this process manages your policies within its window and relative positioning space. Never rely on the system compositor for this. What if the system compositor didn't have a rectangular screen but displays on a globe? Or a hemisphere? Or it wrapped the display around a 3d bunny rabbit? What if it was a compositor for a mobile-like UI where it decided every app window is to be "fullscreen" and mutually exclusive to other apps, displaying only 1 at a time? Relying on and demanding global positioning files in the face of implementing man common UI policies you see today across many devices. Wayland (and xdg-shell) are designed to be as agnostic as possible to the final display policy and thus limit things like positioning to only be subsurface based (relative to main surface). > Sent from my iPhone > > On Jan 3, 2018, at 2:58 AM, Kai-Uwe > <ku.b-l...@gmx.de<mailto:ku.b-l...@gmx.de>> wrote: > > > Maybe you are after a full screen application then.
