If you can help fix this jitterness bug, please pm me with your paypal email and the link to the new jsfiddle. 

I've been trying to fix for about 2 weeks, I've given up.  Only happens when an angle is present on a sprite.

game.renderer.renderSession.roundPixels = false;

Solves it for me.

When camera starts to pan, jitterness comes back

Edit: Forgot to mention that, sorry

[Babsobar]

oh right, camera follow is commented out in your fiddle

[Babsobar]

I got this from the documentation,

follow(target, style, lerpX, lerpY)

Tell the camera which sprite to follow.

You can set the follow type and a linear interpolation value.
Use low lerp values (such as 0.1) to automatically smooth the camera motion.

If you find you're getting a slight "jitter" effect when following a Sprite it's probably to do with sub-pixel rendering of the Sprite position.
This can be disabled by setting game.renderer.renderSession.roundPixels = true to force full pixel rendering.

I can't see the sprites your using, but just know that the jittering happens also with the default box

Yep. Even if we enable roundPixels it still happens. But, if we disable roundPixels it doesn't happen but only jitter when camera pans.  Very nasty

I don't get any jittering with this: http://jsfiddle.net/vnzzfnmg/

Yeah, I tried this way but then the tiles / background in the back become distorted when panning.

Then, using `game.camera.roundPx = true;` will fix the background distortion, but then the sprite's jitterness is back. LOL

Fix the fiddle with some proper assets that show this, because I don't see it on the above.

[WombatTurkey]

Ok.

Here: http://jsfiddle.net/Dillybob/vnzzfnmg/1/

Now, hold down S + D and keep your eyes on the tilemap's background you can see the jitter (when camera pans)

Now do: game.camera.roundPx = true;

The sprite jitter's, but not the tilemap / background

However, if you move the sprite by doing `.x+=speed` instead of velocity, there is no problem whatsoever (except for collisions lol)
