Same here, is painful to create or edit gigs in the gigs pricing page.
It happens in every browser. I think it can has something to do with the new animated tooltip on the right, but I'm not sure.
Only the text input is laggy, not the rest
Seems an interesting idea, though I'm a bit more specialized nowadays (doing graphics and illos for games, both tabletop and videogames), but maybe I can create a gig in that Design Advice, relatively to my specific field.
