UMG Button defects on iPhone 5s not 5

[anonymous_user_642ca581]

can anyone help please?
using UMG i have UI buttons placed in horizontal and vertical boxes, the buttons are white images with alpha and tint is used to set the colour of the image according to gameplay.

everything works and looks ok on tested iOS devices iPhone 5, iPhone 6s Plus and iPad 2

but the iPhone 5s has defective lines on the edges of the buttons, see screen shots

Any ideas?
Thanks

Hi, could you make sure that those textures have no mip maps? In the texture editor set “Mip Gen Settings = NoMipmaps”.

thankyou, i had the textures set to texture group 2D pixels and mip gen settings to from texture group. as you suggested I’ve now set them to texture group UI and no mip map. works fine now.

Thanks again
