Within the ShaderGraph and the VisualEffectsGraph, HDR Color pickers look extremely weird.
The fields work, but the sliders can’t be used. The preview is pretty messed up too.
This appears within Unity 2022.3.27f1 with VisualEffectsGraph and ShaderGraph 14.0.11.
I am also using Odin Inspector 3.2.1, which could also contribute here, although I am unaware of Odin doing anything within VFXGraph or ShaderGraph.
