That was to be less ugly by default, since the background applies to
every subtitle format.

That shouldn't happen.

But since there was some change in the way font size is computed in
regions, and this indirectly applies to grids, there might be an
regression if that's not only macos. (which i can't see with my test
samples)

1 is easy to fix
