Status: RESOLVED WORKSFORME

(Core :: Graphics: Canvas2D, defect)

On macOS, the graph on https://faraday.basschouten.com/mozilla/Speedometer3Dashboard/details.html renders incorrectly: Instead of a stroked circle you get two circles with an offset between them. And there are some glitched circles as well.

Here's a recording of the bad frame which can be played back with player.html from https://github.com/kdashg/canvas-rr/tree/f99f868b80b0328159cddd35352d670fe3ba5e41

This is fixed now. I'll get a fix range and dupe.

I wasn't able to reproduce the problem when trying the 2023-06-08 and 2023-06-09 builds with mozregression.
