Large number of `get_registry` calls at start, and on opening workspaces view #36

wl_registry objects are never destroyed, so this leaks resources and is likely an issue.

Not sure exactly where get_registry is being called. Ideally there should only be one wl_registry instance, but a few in difference libraries is fine.

This issue seems to exist in upstream Iced, when using the wgpu backend, and creating multiple windows.

Looking at Mesa's code, it does seem the Vulkan WSI calls wl_display_get_registry every time you create a surface.

This may be a problem for anything that creates and destroys a lot of Vulkan surfaces.

https://gitlab.freedesktop.org/wayland/wayland/-/merge_requests/388 hopefully will allow this to be fixed in Mesa.
