Glowing entities broken/changed after 1.6.8

[Misquoth]

What happened?

previously making an entity glow would create an outline around the entity. In newer versions nothing happens at all.

enabling / disabling shaders does not change behavior.

issues exists on iris-mc1.20.1-1.6.10 and iris-mc1.20.1-1.6.9

Reporting that issue is still present in 1.6.14+1.20.4 / 1.6.11+1.20.1.

Seems to occur only when using shaders actively with a non-SRGB color space. Hopefully this helps!
