Pattern Rendering Tikz with different viewers

What exactly is your question? This is obviously an issue with the SVG renderer of Firefox that doesn't support all SVG features used in the generated file. There isn't much I can do here.

Thanks for your quick response. I think so too, you can close this item.

@phisp dvisvgm generates SVG but it seems you're talking about PDF?

[F-Phi]

aren't this SVG embedded within PDFs? Yes im talking about PDF and i think the problem lies within the viewer

[muzimuzhi]

No PDF cannot embed SVG (as page content). An SVG has to be converted to another format before being inserted to PDF. And dvisvgm is (only) able to

converts DVI, EPS, and PDF files to the XML-based vector graphics format SVG.
source: https://dvisvgm.de/

thus any PDF-based rendering differences, rather than SVG-based ones, are out of the scope of dvisvgm.

(already off-topic but to make things linked/connected...)

Turns out it's a pdf.js bug, see mozilla/pdf.js#16038. pdf.js is a pdf reader in javascript and is built into version 19+ of Firefox. You can find a pgf-tikz workaround in the attachment dvisvgm-gh228.tex.zip in that issue, or in pgf-tikz/pgf#1180.
