Hi all, this is the windows package, the blur brush may not work properly at the moment, but the normal smudge brush should be sufficient, I think the best way to keep the current blending effect is probably to use XSIMD for code optimisation, which may require the help of the official developers to do this; the pixel brush engine brushes need to select the spectral blending mode, the smudge brush needs to be turned on in the brush settings to use the new version of the smudge brush engine, and the spectral blending needs to be under the linear profile to blend the correct colours: Krita
