Hi!
I just discovered that all my sprites are a little bit transparent for some reason. I can’t really explain it very well so here is a picture.

Look carefully on the blue bricks where the trees are. You can see the tree outline through them. My sprites have 0 transparency when I check them. Why does this occur?
Thanks in advance
check your graphic program the sprites might be already transparent the problem not with unity.
For anyone that might have a similar issue try moving the Z coordinate of your background away from the camera (so from z=0 to whichever positive number ex. 1) if you’re using an orthographic camera.
I know it’s too late but for someone who looking for answer: You can must select your sprite and then in the inspector change the format from compressed to Truecolor.
