No sure when it happend and how, but my Gravity forms look flat. Doesn't look like the correct CSS code get's loaded for the text boxes. Check it out here:

I'm running Thesis 1.8.2 and WP 3.2.1, and newest Gravity Form plugin.
This is a theme-related style problem, not something that's Gravity Forms specific. Gravity Forms doesn't set any specific border styles on inputs.
That's the fun part of CSS rules, the browsers don't always interpret or render them the same way. The problem is coming from a border-width property ( border-width: 0.071em; ) on line 246 of your layout.css file. Chrome doesn't apparently render this odd value properly so it simply shows no border.
You can disable that property in that rule, or change it to another value that you prefer and it should resolve your display issue.
