I noticed a minor visual bug involving the rotating ritual sigil beams effect. If an active ritual is nearby then it seems to render a duplicate beam effect maybe a few hundred blocks away from the player and it tracks wherever they turn with the camera. It's not quite centered with the crosshair, in my case it was above it a fair amount. I tested with various shaders and without any at all. Every shader I tried except for the PSX shader (which is pretty minimal in its effects) had this bug persist. I haven't gone through the effort of testing what common effect between shaders may be the cause. Now, what makes it go away seems to be when the player moves away from the ritual about 50 blocks or so. The beams sort of zig zag in a direction as if they're moving on the game's grid and eventually disappear. I guess this is a pretty minor bug, but I thought I'd report it for awareness sake.
