There are ugly effects scrolling the homepage when:

1 - I change the browser size, smaller

2 - I scroll along the homepage and i see the images in callouts, slider... their scrolling is cut before arrive the limit of the browser window. The texts in that modules, callout, slider.. scroll well but not images.

In a browser full window my homepage is scrolling well, but not with smaller sizes. Obviously, in a tablet the scroll is not correct as well.

In the demo page at Nuevvo.com you can see this effect as well.

Responsive?

I just tested it with my iPad and it seems to scroll well.

If you want to disable the effect you need to remove these lines from your /templates/matchbox/js/behaviour.js file

Done. But... the same. I don't see any change. Disabled? Not, i think.

I would like those components, modules, (callouts,sliders...) would be just simple images full-width and scrolling just like simple images, without any scroll "fashion" effect. Is it possible? How?

I do not think I understand you.
There are two types of animation.

One that moves the items (text elements, team members etc..) up a bit once you scroll down and one that uses a parallax effect for the images.

Which one (or both) do you want to disable?

Then, It must be the parallax effect. In my nexus 7 and nexus 5 with chrome the effect is strange, the image grows step by step while you scroll up or down but not from the end or the beginning of the window, but from the middle or so of the screen. If that is parallax then i don't like parallax.

So, can i disable parallax?

So disregard my previous posts and rollback any changes.

In the same file, behaviour.js locate the following code.
This will remove the parallax effect.

Right. Perfect. Much better :)

Thanks.
