https://ci.chromium.org/buildbot/tryserver.chromium.win/win7_chromium_rel_ng/142774 (note that the build succeeds because the test flaked on the 'without patch' run of webkit_layout_tests). It appears that the test timed out: https://chromium-swarm.appspot.com/task?id=3ccae05082deae10&refresh=10&show_raw=1 17:33:23.834 3716 [3883/5358] fast/canvas-api/canvas-toBlob-case-insensitive-mimetype.html failed unexpectedly (test timed out) 1 Looking at the test (https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/fast/canvas-api/canvas-toBlob-case-insensitive-mimetype.html), my only thought is that somehow toBlob takes a really long time or never returns in some case?
Will take a look
The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/b26c6e36b15bdfc8368e9851d5468b6383137e08 commit b26c6e36b15bdfc8368e9851d5468b6383137e08 Author: xlai <xlai@chromium.org> Date: Fri Apr 20 19:41:15 2018 Move all toBlob layout tests to fast/idleToBlob Both canvas.toBlob() and OffscreenCanvas.convertToBlob() require support of idle tasks, which are only enabled when threaded compositing is turned on for layout tests.
