I can't figure out what is causing this, and why it is only affecting some of the sprites.

Are you sure there isn't something strange on the map for those sprites? Like two on top of each other or something, or some other property which makes them different?

I sent the example map, you can see it's normal.
Originally I wanted to post ,,all flatsprites appear glitched" but when I created this demo of the bug, the bug just didn't happen with my freshly made sprite "FLATSPRITE", only with the grass (I made them both in paint.net the same way). My only idea is that it might be related to complexity? the one with red text basically only has red color, the grass sprite has at least 3 colors. Or - I don't remember if I modified the scale of grass sprite anyhow.
But it happened to all my sprites for me which I put under 3d floors. Only this red text is different, and I don't know why.

I even tried if one of the flags I put, such as +NOINTERACTION is related, but for me it didn't make a difference.

(By the way sorry, I accidentaly posted with temporary profile - this is the one I wanted to post with)
