Outlines are not smooth

Describe the bug 📝

When using the postproduction.customEffects I want to add an outline to my fragments as without it looks blank and feels somewhat difficult to identify where specific elements end or begin.

To add this I am enabling postproduction, set the customEffects.linecolor and exclude my grid mesh from this customEffect. I also create my renderer with the WebGLRenderParameter "antialias: true" from which I hoped to smooth the edges my elements...

The elements on their own DO have a smooth edge but the outlines are still pixilated like shown in the following screenshots:

*postproduction.enabled = false (to stop drawing outlines)

*enabled postproduction and everything I was talking above:
