Problem with UMG on PixelArt Sprites

Hello to all who share with me the pleasure of working with the unreal engine for some time been working on a 2D PixelArt SideScroller game and had some problems on the interface.
As shown below:

Does anyone have any idea what this might be blurred effect pixel art of the UMG?

Thanks so much!

Slate didn’t respect the filter setting in 4.10. I believe I fixed that in either 4.11 or 4.12, can’t recall which one.

I tested in version 4.12.5 and you were right ! Many thanks for the reply! you saved my life :smiley:
