Bug 234536 – [GPU Process] webxr/high-performance.html fails on iOS

• Status: NEW
• Component: WebGL

[Jon Lee]

When turning on full GPU Process for iOS these WebGL tests fail:

webgl/max-active-contexts-webglcontextlost-prevent-default.html
webgl/many-contexts.html
webgl/max-active-contexts-oldest-context-lost.html
webgl/2.0.0/conformance/reading/read-pixels-test.html
webgl/max-active-contexts-gc.html
webgl/max-active-contexts-console-warning.html
webgl/many-contexts-access-after-loss.html
webxr/high-performance.html

Latest EWS run adds these crashes:
fast/mediastream/getUserMedia-to-canvas-1.html
fast/mediastream/getUserMedia-to-canvas-2.html

[Jon Lee]

Timeout:
webgl/1.0.3/conformance/state/gl-object-get-calls.html

[Jon Lee]

After bug 222410 lands, the remaining failures here will be

webxr/high-performance.html [ Failure ]
webgl/1.0.3/conformance/state/gl-object-get-calls.html [ Timeout ]

[Jon Lee]

webgl/1.0.3/conformance/state/gl-object-get-calls.html is currently timing out on the regular iOS bots; it will pass once the WebGL flag is flipped on.

That leaves the remaining XR test.

webgl/1.0.3/conformance/state/gl-object-get-calls.htm is now a constant timeout seemingly after r291751.

Curious if css3/color-filters/color-filter-column-rule.html is related

Also if these failures:
animations/stop-animation-on-suspend.html
editing/spelling/toggle-spellchecking.html
fast/css/button-height.html 
imported/w3c/web-platform-tests/css/mediaqueries/mq-gamut-002.html 

Are also due to gpu process

Please file separate bugs for these if they don't already exist, and not pile onto this bug. This bug is specifically about the WebXR test.

This seems to be debug only, after turning full GPUP on by default.

This is flaky, but more reliably failing on debug, even before turning full GPUP on by default.

> editing/spelling/toggle-spellchecking.html

This was flaky failing before, but is now happening more frequently, and is appearing now in debug.

> fast/css/button-height.html 

This is an iPad only failure that existed before.

> imported/w3c/web-platform-tests/css/mediaqueries/mq-gamut-002.html

This is an iPad only failure that existed before.
