Pixelwobble is when you have a slow scrolling game (or move the mouse pointer slowly in WB) and you see the pixel sizes "change" from square to rectangular. Some people don't mind that I hate it.

The Sharp_Bilinear_Simple will give you a sharp image like my attached sharper image without wobble. Notice there's still a bit of blur, unless your PC screen size is an exact multiple of the Amiga screen size and you use those factors in the shader.

Note this works only IF and ONLY IF your integer pre-scale numbers are not too large (depends on your PC screen size and Amiga screen size) see OP.
With 1:1 + null filter I eliminated that wobble effect (I can see better square pixels), with a very slight blur.
With 1:1 + Sharp Bilinear Simple is very close to previous, but not identical.
