antiqueatlas-5.0.3-fabric

When holding an Atlas on hand, having the overlay shown, the console gets spammed with opengl errors until the Atlas in no longer the active item on hand.

Do you get the same error also with only Antique Atlas (and its dependencies)?

Yes.

I cannot reproduce this on my system, but please try whether 935826c fixes this issue for you.

Seems fixed:

By the way these are my specs:

Maybe the Intel integrated graphics was the problem and why you could not repro? Just guessing.

The actual problem was a (de)obfuscation mishap for one OpenGL function that happened during the port to fabric. I've got a dedicated AMD card, so it might be a more relaxed driver or something.

I'm going to release a new build soon.
