Shading effect issue when resizing if grouped

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

  • This is another one of Corels pesky ass refresh bugs, makes the program a PITA to use. You'll find them in lots of places like the edit bitmap feature, immediately after you import an image you need to save the file to use all features also the object docker. So if you see weird try saving or saving , closing and reopening orvw refresh of some type.
