Created attachment 468912 [details] The two images referenced in the bug report. Steps to reproduce: * Open Safari and close all of its windows * From the Develop menu, run "Empty Caches" (Note: This is an important part of reproducing the bug consistently) * Open a window and open https://daveverwer.github.io/WebKit-SVG-bug/ * Close the window, but don't quit Safari * Open a window and open https://daveverwer.github.io/WebKit-SVG-bug/ Opening the page the first time shows the first.png, opening the page all subsequent times shows second.png.
I cannot reproduce this consistently as described on an M3 Mac with macOS 14.2 beta. But I do see both renderings intermittently when simply Cmd+clicking on the link here. What's particularly weird is that when I have two tabs with different renderings, reloading (with Cmd+R) never changes either of those! Which implies some kind of Web process state, not a timing or HTTP cache issue.
"Empty caches" fixes this, so it's something about the images being cached.
