I'd be interested in steps to reproduce this.

I can't remember seeing anything weird with headbands, or other equipment for that matter, but maybe I forget things.

I'm currently playing with a resolution setting of '2560x1440' and drawing precision of '5120x2880', and the only obivous weird thing I can remember is parts of water in Bastok Markets.

I play via Wine on Gentoo Linux though, so that might make a difference. :]
