Why are some of the textures so low quality? (1.5.6)

[lukkyb]

Here are some examples i saw in the empire towns (havent been elsewhere its my first start of 1.5.6)



here both (Above) the icon and the outfit seem very low quality



and here (Below) the head gear is ok while the icon is low quality

has anyone else notcied this and is there a reason for this
