I’ve a problem with UMG images (both from texture and materials) when running them on device (ipad air) they have weird border around the texture.
I’ve a problem with attaching a image here so I’ve uploaded screenshots over dropbox - you need to zoom in to see the border. Repro is simple - create an texture (I’ve attached mine) with alpha and assign it to umg image widget.
Here you can find the texture source, uasset file and screenshot: Dropbox - Error
