UMG Image Low quality and getting cut off at edges.

I have this simple health icon:

When I create an image element in UMG, it shows this instead (No grey background, that is just the wall behind it):

When I start the game, it looks normal, and after about 1/2 of a second, it starts to get larger and more smudged. What is happening? I have been using UE4 for some time and I have never seen this.

Looks like the image is being called over and over and multiplying on top of itself. Is there anything in your script that could be calling it on a loop?

Thank you @McJeff ! I had accidentally hooked add to viewport up to event tick instead of begin play.

Huzzah! My pleasure!
