Does this only happen with the dark theme? Because with the darker theme it look good to me.

First, the original design by @horst3180 uses light separator for dark menus, and IMHO there would have to be a very good reason to change that.

Second, any such changes would have be applied to all themes, i.e. all gtk3 theme versions, gtk2 theme, gnome-shell theme, etc.

[NicoHood]

I like the idea.

Agreed - this should be merged only when similar changes are made for gtk2 gnome shell etc otherwise we get a inconsistent approach.

@cynecx What's the status on this? Can you implement the change for GTK2 also so it can be merged?

[fossfreedom]

This PR diverts from the original arc design. I don't see a consensus here and it needs more work anyway to make it GTK+2 compliant. So I'll close this for now.
