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.
