Bug 276005 – [ iOS Sim, x86_64 ] 3 webgl canvas textures conformance tests are constantly failing.

• Status: NEW
• Component: WebGL

[Ben Schwartz]

The following three tests are constantly failing on iOS simulator when the host Mac architecture is x86_64:

webgl/1.0.x/conformance/textures/canvas/tex-2d-rgba-rgba-unsigned_byte.html
webgl/2.0.y/conformance/textures/canvas/tex-2d-rgba-rgba-unsigned_byte.html
webgl/2.0.y/conformance2/textures/canvas/tex-2d-rgba16f-rgba-float.html

HISTORY (it appears passing because none of our infra tests on x86_64):

https://results.webkit.org/?platform=ios&suite=layout-tests&suite=layout-tests&suite=layout-tests&test=webgl%2F1.0.x%2Fconformance%2Ftextures%2Fcanvas%2Ftex-2d-rgba-rgba-unsigned_byte.html&test=webgl%2F2.0.y%2Fconformance%2Ftextures%2Fcanvas%2Ftex-2d-rgba-rgba-unsigned_byte.html&test=webgl%2F2.0.y%2Fconformance2%2Ftextures%2Fcanvas%2Ftex-2d-rgba16f-rgba-float.html

REPRODUCIBILITY:

I was able to reproduce this issue on iOS simulator (17.5, x86_64 machine) ToT using the following command:

run-webkit-tests -v --ios-simulator webgl/1.0.x/conformance/textures/canvas/tex-2d-rgba-rgba-unsigned_byte.html webgl/2.0.y/conformance/textures/canvas/tex-2d-rgba-rgba-unsigned_byte.html webgl/2.0.y/conformance2/textures/canvas/tex-2d-rgba16f-rgba-float.html

REGRESSION:

It looks like the first two tests have been failing since introduction in iOS 16. The last test appears to have started failing after the ANGLE re-import at 267605@main.
