BLUR.

Does anyone manage to use blur successfully ?

HIse gets very sluggish when enabling blur,either I am doing something very wrong or its not usable ?

Any tips or tricks ?

@lalalandsynth Been looking into this a bit more. The issue is HISE only gives us box and gaussian, and both are too heavy to run live — fine for a one-off bake, useless on anything that redraws.
Over on the JUCE side the go-to is Stack Blur, and there's a mature module for it (melatonin_blur, MIT licensed, now under the Tracktion org). It's a Stack Blur / convolution implementation built specifically so you can throw a bunch of drop shadows and inner blurs on a vector UI and still hold 60fps. Since HISE is JUCE under the hood, seems like a fast blur path is very doable.

@lalalandsynth HISE has melatonin blur for a couple of years, but I think it's only used by the drawShadowFromPath functions.
