Image disappears when Canvas is set to 'Pixel Perfect'

I am getting a really strange behaviour. I have an image in my UI composition and, somehow, setting the Canvas to ‘Pixel Perfect’ makes it disappear.

I made a shot screencast to represent this:

Any ideas what causes it?

I had the same problem. Turns out that my image’s Z scale was set to 0, which was fine when it wasn’t pixel perfect, but when pixel perfect was turned on the image disappeared.

Try setting the image’s Z scale to 1 if not already.
