Scrolling on Mac is very slow and stuttery

[tomoakley]

Hi,

Trying out a few new code editors as I'm finding Coda 2 has got a bit stale. Loving Brackets so far :)

One thing i'm finding a bit annoying is that the scrolling seems very stuttery and completely non-smooth. While I completely appreciate that Brackets is still in Alpha/Beta, I think scrolling performance of an editor should be good so you can move around code quickly. I have no experience of OS X development, but it seems to me that Brackets doesn't use native OS X scrolling APIs like rubber-banding (when you hit the top of the window and it carries on a little) and the momentum-scrolling that works a little like iOS. Try using Coda or Sublime and then compare with Brackets (preferably with a big file), to hopefully see what I mean.

Btw: I'm using one of Apple's Magic Trackpads. Not sure what it's like to use a Magic Mouse/normal mouse.

Thanks,

Tom Oakley

@njx has noted that this is particularly evident with retina displays.

Scrolling performance is definitely on our radar. In the near term, we're going to be taking some measurements on a few things including scrolling, and then taking action to improve performance.

I'm closing this bug not because we're not interested, but because scrolling and other performance issues are already on our backlog.
