I have noticed several people online saying that antialiasing has been causing problems recently on Safari, but I couldn't find a bug related to it...

This page loads, because antialiasing is disabled.

This page crashes because antialiasing is enabled.

Note: we also have the same behavior in Chrome on Apple devices, so I am guessing that the issues is in the ANGLE/Metal layer that they both use.


Note2: this bug is using the same repro scene as this other issue: https://bugs.webkit.org/show_bug.cgi?id=239015

This is a duplicate of the other WebGL MSAA bugs. The test case loads in Safari Technology Preview Release 143 (Safari 15.4, WebKit 17614.1.7.7) on an M1 Mac and  doesn't load on Safari Version 15.4 (17613.1.17.1.13).
