Swapping textures in a dynamic material instance with preloading

I have a bit of a weird problem. I have a material fed with only one texture parameter. This texture will be swapped out and replaced with 10 different textures from a blueprint. When you press a button the blueprint will cycle through the images and display them on the mesh.

I have a slight problem though, and I am not quite sure where it’s coming from. When I press the button the image changes, but for 0.1 seconds the image is blurry and after that it returns to a normal state. It seems though as if it does not have enough time to finalize the image or something similar. So, does anyone know where the problem might lie? Can I preload the textures somehow?

The textures are 2048x2048, they have streming enabled and so on.

Cheers!
