    <thetext>REGRESSION(Safari 15): Rendering error on certain hardware using ANGLE OpenGL (gltf corrupted geometry)

https://github.com/mrdoob/three.js/issues/22628

&gt; To reproduce (on a machine with a Radeon Pro 555) follow these steps:
&gt; - Download this geometry: https://github.com/HSF/phoenix/blob/master/packages/phoenix-ng/projects/phoenix-app/src/assets/geometry/ATLAS/Barrel-Toroid.gltf
