Someone here on the forum has already realized that when the shading is grouped when it grows it distorts the pixels, if it is not grouped it looks good. I know that this error is happening in Corel 2020 and 2019, in other versions I don't know.The new internal shadow effect of Corel 2020 even grouped does not happen this error when making it bigger.Does anyone know any solution to this problem?I made a sample video
