Safari does not render 3D CSS sites well. The following site:
https://garethheyes.co.uk/

This site works fine in Chrome and Firefox but crashes on mac os and iOS. It’s very glitchy. The site uses Houdini properties and the :has selector with media queries to support browser that do not have the features. Safari shows a black page which I think is because of the fixed positioned divs. If you then navigate with the controls provided it starts to work then often crashes.

I wasn't able to reproduce any crashes on macOS. The page goes black again sometimes (but controls don't disappear).

I have seems similar looking issue (where half screen is covered with weird black triangle) in Interpolation test case.

I am going to CC - Antoine and Matt - since they fixed some interpolation and transformation related bugs in the past and where I faced this issue was also around it.
