Today droplet won't redraw the gutter when breakpoints, warnings or errors are added. This is because an optimization skips rendering each line of the gutter when that line's position has not changed.
The solution proposed here is to remove the optimization. I'm unable to notice a difference in performance when switching between text mode and block mode with a full screen of code in App Lab, so I don't think there will be a performance regression here.
