Issue Description

When using the Complementary shader with Iris the measurement wont be visible. Without shader it works
fine, so the shader is breaking the rendering.

Two other players on our server got the same issue.

Additional Information

No response

Ok, so still haven't heard back from the Iris team, but I do have an update from my own tests:

Complimentary isn't the only shader pack preventing the Measurements UI from showing up. It looks like Astralex, BSL, Continuum, FastPBR, Kappa, Musk Rose, Noble, and Sildur's are all causing it.

I did find one shader pack that didn't cause this bug when used: Chronos. I'm not sure what that one doesn't have that the others have, but that may be the key here.

@Mrbysco @GeneralMine So, the Iris support team said that, based on my findings above, it may be an issue with the fact that most modern shader packs (including all the ones I tested above that produced the bug) use forward rendering, and the reason Chronos was the odd-man-out is because it's one of the few that uses deferred rendering. Hopefully this helps.

Update: Never mind, this might not be the cause of the issue, as another Iris support team member clarified that Kappa and FastPBR are actually deferred.

I looped the Iris team in (via their Discord server), so we'll see if they have any insight.

I think this is happening in Fabric 1.20.4 as well.
