Editableimage not scaling to my screen size & reflections coloured wrongly

self explanatory issue ive got here, been making a path tracer and the editableimage im using just randomly stopped scaling to my screen size about a month ago

im downscaling the resolution of the editableimage to about 1/16th the game window size, but even trying it in full resolution yeilds the same result. an editableimage with a visual scale below 1/16th the window resolution. even when i set its imagelabels size to the full screen, on top of its holder element with the same scale



this is the ui setup i have going rn (the corner frame is just for debugging a separate bug i had)
image

and this is the code where the image size is set. not one time do i change the image size anywhere else, and this is the only size edit ive made after checking through all module scripts behind this

removing the NewImage.Size line also yields the same result. i actually added it to try fix the issue

i also have a second issue where all my colours within reflections are wrong.

anything reflecting the sky returns as the reflective parts colour, and anything reflecting an objects colour is returned as pure black. been struggling with this issue for close to 2 months now cause im genuinely stumped about the issue
