Pixelation when adjusting opacity
Hello,
I'm using PS 21.2, and I'm having an issue with a layer: when I try to set opacity to let's say 64%, the layer is all pixelated.
Picture 1 shows my gray layer over the image, which is totaly pixelated (it is just a #444444 gray rectangle, the one I'm trying to set at 64% opacity)
Picture 2 shows another layer (the red disc with the iconwhich can correctly be set to another transparency level without any issue.
What am I doing wrong?
Thanks in advance!
