On Firefox there's noticeable lag, and non-straight lines look kind of weird (feels like it's trying to make non-straight lines out of bunch of straight lines).

On Firefox there's noticeable lag, and non-straight lines look kind of weird (feels like it's trying to make non-straight lines out of bunch of straight lines). On chrome there's no lag, but every time I draw something, all other elements I drew before change colour. At first to bright green, then they just fade to white as I draw more lines or whatever. As it is right now, it's definitely not a good 'replacement'.
