Maximizing Launchbox on a 21:9 monitor

Hey, feels like a dumb question. But is there a secret sauce (setting) to getting Launchbox to maximize on a 21:9 monitor? When I click maximize, it spans what looks like 1.33 monitors!

I'm embarrassed to report this as an issue to Jason if it's just something that is affecting my environment. Are other folks using Launchbox on an ultrawide monitor without issue?

Thanks.
