Blur imagenes only in Apple devices (not Retina)

[David Y.F.]

Hello,

I have a problem with blurry images ONLY with Apple devices, even when screens are not Retina.

The imagen in Home Featured Products Module, and only there, is lightly blur.

The images are high resolution when are uploaded (960x960) and aspect ractio is perfect (230x230).

The same image in any other device is correctly displayed.

Images settings are placed in PNG at max quality (0).

I've read this:

Even uploading image are high quality it doesn't work.

Image is at right bottom corner, id 56.
