path-dash.svg

An SVG path with a dash is rendered incorrectly in Safari. The result should look like a dashed rectangle. See the attached test case path-dash.svg and the screenshot safari-16.1.png.

Tested on Safari 16.1 and Tech Preview Release 159 (Safari 16.4, WebKit 17615.1.12.130.1) (Intel and Apple Silicon Macs).

Chrome 108 and Firefox 107 render the path correctly. I also tested on macOS 10.6.8 Snow Leopard Safari version 5.1.10 (6534.59.10) and it renders the path correctly (see the file safari-5.1.10.png). Safari 10.1.2 on macOS 10.12.6 Sierra doesn't render the path correctly, so it seems that the bug appeared somewhere between those two versions..

Curiously, when I Cmd+click on the test link, and switch to the new tab, it looks broken for a second, and then repaints (mostly) correctly. There is still a difference in that corners are rounded.

That sounds like accelerated drawing vs non-accelerated drawing.

Bug is in a component below WebKit.
