Images as planes appears grey through grease pencil, while in draw mode

Blender 2.93.0
Ok I am back again and still incompetent. this may be a non issue because I haven’t really attempted to render it yet. im aware my drawing is bad there are A LOT of mechanics I need to learn to improve

I have a 2D animation using the grease pencil tool.
I want the background sky to be an image (thus images as planes)

When in object mode everything looks just dandy
when I switch back to stroke and draw it has this grey border

-viewport seems to do little that is useful
-the most useful info I could figure out is that if “show backface” isnt selected the whole images looks like that
-if alpha is 0 the overlap is invisible as well

Feel free to ask for more information! I am functionally a warhammer ork given blender tools, ie. I am aware I have no idea what I’m doing.

EDITS: 1. turns out its not invisible if alpha is 0 my bad it just blends in with white

It does appear to be a non issue it did not show up in the render, my bad.
