On the other hand, if you see an optimization that would improve it on AMD GPUs with ANGLE's Metal backend - that would address the primary concern of the test, which was designed to expose issues with AMD GPUs on Apple's OpenGL driver. 1851248 2 webkit-bug-importer 2022-03-15 06:07:17 -0700 <rdar://problem/90302438>
