Halftone filter on a shape, uncovers the edge

[PepGold]

I have an issue with halftone pattern inside shapes that I can't resolve. 

If I create a basic shape like a circle or square etc. fill it with a black to white gradient, or a solid color and apply a halftone filter to it. It does create a halftone pattern of the gradient that you would expect. Also adds halftones at the edge of the shape. So it doesn't fade out to white. 

How can I get rid of the border/edge?

Add a black filled shape as a mask.

while this works  great in the specific situation, I’m wondering if there is a specific reason that you specify black? As far as i know the matter, the color is irrelevant when vector shapes are used for masking. Only the alpha channel information is used.

So i sometimes copy the basic shape and use it as mask, don’t care for colors at all. For the color at all. 
 

Please note that for pixel layers or mask layers, the color actually matters, and black would hide. So i tend to use white instead of black, to avoid bad surprises when you need to rasterize a vector shape, or use blend ranges.

Add a Fill Layer from Layers menu, and move that layer to the bottom, fill it with pure white color, problem solved.

I'm trying to make simple halftone patterns to use in some vector illustrations, but I keep getting a border of heavy dots where there is no border.

Is there anyway of doing this without elaborate workarounds? At this point I'm about to dump trying to get this working (without elaborate workarounds) in Designer/Photo and just move to Illustrator and Astute Graphics' wonderful 'Phantasm' plugin for the (actual vector) halftones.

As much as I love working in Designer (for basic vector drawing), whenever I need to do anything 'different' I get so frustrated with the limitations of these apps. What makes it worse is that many of these issues are going back YEARS, and we have absolutely no idea if they'll ever be addressed.

a very simple and easy workaround: 

1. use a rectangle as base shape, having the intended color / gradient / image or whatever content you want.
2. add the HT filter child-nested
3. Use another shape as mask.
4. the base layer must be larger than the shape used for masking.

2. add/move the HT filter above (not nested!). if required, use a group.

Thanks @NotMyFault that works, but it's a bit clunky and makes management of the gradients, halftones, etc a bit more complicated.

I'm just seriously annoyed that every time I need to do something a wee bit different I continually run into the limitations and long standing issues of these apps. I lost an hour futzing around with and posting this issue only to realize that the workaround won't work for my workflow (I need it to work on the exact shapes themselves). There comes a point whereas much I a LOVE certain aspects of the Affinity suite, there's too many problems that continue to suck time to continue to rely on it.
