    <thetext>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.</thetext>

    <thetext>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</thetext>

    <thetext>(In reply to Matteo Flores from comment #6)
&gt; webgl/1.0.3/conformance/state/gl-object-get-calls.htm is now a constant
&gt; timeout seemingly after r291751.

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

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

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

&gt; 
&gt; Also if these failures:
&gt; animations/stop-animation-on-suspend.html

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

&gt; editing/spelling/toggle-spellchecking.html

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

&gt; fast/css/button-height.html 

This is an iPad only failure that existed before.

&gt; imported/w3c/web-platform-tests/css/mediaqueries/mq-gamut-002.html

This is an iPad only failure that existed before.</thetext>
