Addendum:

Granting socket=system-busvia flatseal leaves me with

flatpak run org.signal.Signal

Had the same problem.

I noticed while updating that signal added a new permission: fallback-x11
removing this permission with flatseal fixes startup for me

[maymage]

I confirm... removing the permission for fallback-x11 makes Signal work again as expected.

[Vinnl]

I think this was fixed by #285.

[sebastian-de]

I assume --socket=fallback-x11 should work as soon as v5.38.0 is released, since it contains an update to electron 17.3.1, which should fix several issues on Wayland.
