What Application are you using? 
Photo

Are you using the latest release version?
v2.1.0

Can you reproduce it?
Yes

Does it happen for a new document? If not can you upload a document that shows the problem?
Yes

hardware acceleration
Same issue with both.

What happened for you (and what you expected to happen)
Using a Procedural Texture live Filter, with alpha being the only channel being applied to create weird artifacts on outlines on elements under the texture, it happens whether it's a mask or a child layer inside a group

Child Layer

Procedural Texture can also just be 0 with A Channel:

can you please add the actual test file?

iPad Air Gen 5 (2022) A2589

Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

I use iPad screenshots and videos even in the Desktop section of the forum when I expect no relevant difference.

the issue is not specific to procedural texture filter. You can create similar artefacts using

  • channels mixer: reduce "offset" on alpha, or alpha input
  • level adjustment: reduce black / white level
  • or curves adjustment.

A trigger condition is the group layer with blend mode "passthrough".

The main point is that it causes the Outline Layer Effect on an object inside the group to look buggy, I would expect the Procedural texture to stay on top the same way that it does on parts that aren't the Outline Layer Effect

 

I was also not able to replicate the artifacts you mentioned 🤔

 

I did find a workaround that uses a Fill Layer as the base, you then use the Procedural Texture as a clipping mask, and either duplicate linked the layer in the group or go over to the Designer and make a symbol, which you can then use as a mask on top of the Procedural Texture

Here my test file, using channels mixer to show issues on alpha channel.

another issue: if you reduce fill opacity below 100%, the pt filter on alpha stops working.
