Compositors based on wlroots should have LayerShell functionality, allowing Discover to Just WorkTM
Wayland without wlroots (Gnome,Weston) removes or underimplements several features that are used to create this overlay, notably:
- Input shapes / click through. Some compositors fare better at this than others
- Set above windows. This can't be enforced by the app itself
- Borderless. Some compositors add a border despite requesting unbordered.
- Custom position. This is not part of wayland spec.
GDK_BACKEND=x11 discover-overlay
Using the compatability layer fixes a few of the above issue.
