1777592 - Series of gradients clipped to transformed text fails to render in Firefox

Status: NEW

(Core :: Graphics: WebRender, defect)

Attachment: test.html

Ran across this html+css thing on a website and noticed that only the first 3 characters render in Firefox. They all render in edge. (I'll attach screenshots). The text is all there in the correct places so if you drag-select to highlight it, you can see it - it's just not rendering.

Glenn, is this related to your clipping work?

Unlikely, but possible. Would it be possible to find a regression range (see https://mozilla.github.io/mozregression/ for more information)?

This repros on a build from 2020, so not a recent regression.

The text ends up rendered using a blob images so webrender gradient aren't involved.
