How to remove projector artifacts?

I have a projector that projects a specific texture towards the ground. However, I get this effect that I assume is an artifact going off the cardinal directions and I don’t know how to fix it. Currently, my projector texture cookie has a 1 pixel transparent border and the image is set to be clamped. I tried looking online but so far, I found nothing and that also includes looking at a blog that talks about it.

Had same problem @RayDawg - turning off mip-mapping (under advanced texture type) seems to be the fix.
“cursor” does this underneath but also makes texture readable and bypasses sRGB sampling.
