Lots of SVG drawing is heavy on the latest version of Safari. Chrome, Firefox and Microsoft Edge don't have this issue. I noticed this issue on November 1, 2022. Live demo with steps to reproduce https://jsfiddle.net/ps51q4wy/3/ Affected browser(s) Safari 16.1(17614.2.9.1.13, 17614)

Thank you for the report! Could you please Thank you for the report! Could you please add some more details to it? - What do you mean by "heavy"? Are you finding it to be slower than in other browsers, or something else? And if it's slow, how did you measure? - Is this known to affect anything besides this test? - What hardware are you using to compare?

- I noticed that rendering is slower than other browsers when viewed with safari. - It happens when I draw a chart with a Highcharts (https://www.highcharts.com/). I contacted Highcharts, but was told that it was a Safari bug (https://github.com/highcharts/highcharts/issues/18089) . - I used MacBookPro. MacOS version is 12.6.1.
