No response

This is also the case with the latest release:

Disabling the shader makes it visible:

This is Sildurs Vibrant:

The death beams are related to #773.

The dragon itself is caused by the entity_alpha shader not being properly supported on 1.17, because the effect works by changing the threshold of the alpha test, but Iris puts in a hardcoded alpha test.

I'm just gonna put this here for anyone else

The purple beams part has been addressed on 1.16.x in the "bulletproof state tracking" branch. The dragon going invisible part is a separate issue to 1.17.x.
