1869002 - shape-rendering not working for <line> in SVG (always crispEdges)

Status: UNCONFIRMED

(Core :: Graphics: WebRender, defect)

Description

[David Gausmann]

Attachment: line.htm

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:120.0) Gecko/20100101 Firefox/120.0

Steps to reproduce:

I am drawing a line with inline SVG in a 45 degree angle.

Actual results:

The line is drawn without antialiasing. Even with the "shape-rendering" attribute no antialiasing is used.

Expected results:

Antialiasing should be used. In Chrome the behavior is exactly like expected.

The missing anti-aliasing is easier to see, if you take a screenshot and paste it into a graphic program, where you can zoom in.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Nical, Jeff, do you know who would be best to look at this? I guess it's blob rendering via Skia, would that be right?
