I’ve encountered the problem with both .png and .jpg, so the format doesn’t appear to matter. Unfortunately I cannot share the .skp file or the textures as I’m presently working with stuff that’s under NDA. I’ve uploaded some screenshots that help illustrate the problem, though.
This is a screenshot taken of a segment of one of the textures I’m using as it appears within Photoshop, Affinity, and Preview.
Since I’m a new user and can only put one image per post, this is gonna take a few posts…
