With https://chromium-review.googlesource.com/627551 now appears to be working properly.

That was a good catch, and seems to have been plaguing this bot for several runs, but the main issue seems to still be present --

That patch first landed on this bot with build 10603, which was red, and all subsequent runs have been red as well.

Still seeing failures on this bot in
(1) accessibility/element-role-mapping-normal.html
(2) css3/filters/effect-reference-colorspace-hw.html
(1) css3/filters/blur-filter-page-scroll-parents.html(3) storage/indexeddb/objectstore-cursor.html

I'll disable the new ones with multiple timeouts:

inspector/tracing/frame-model-instrumentation.html

and see if we can't get a green run out of this bot.

(And storage/indexeddb/objectstore-cursor.html)

I am disabling css3/filters/effect-reference-colorspace-hw.html in https://chromium-review.googlesource.com/c/chromium/src/+/628736 (I did a similar analysis in  issue 758124 ).

out. Marking the test as [ Pass Failure Timeout ].

waiting for a rAF each time.

Wait for double rAF before capturing output.
