Instruments tells that there are "misaligned images" which are animated by core animation.
Quartz allows you to draw at fractional pixels (recall that CGPoint takes CGFloats, not NSIntegers), but it's more expensive and tends to create a bit of blurriness. You can't really draw on a fractional pixel, so Quartz has to do anti-aliasing to pull it off. That takes time and certainly would hurt Core Animation/graphics performance.
Quartz will not warn you that you're drawi...Read Full Post »
