Issue description

"virtual/gpu/fast/canvas/canvas-composite.html" is flaky.

This issue was created automatically by the chromium-try-flakes app. Please find the right owner to fix the respective test/step and assign this issue to them. If the step/test is infrastructure-related, please add Infra-Troopers label and change issue status to Untriaged. When done, please remove the issue from Sheriff Bug Queue by removing the Sheriff-Chromium label.

We have detected 3 recent flakes. List of all flakes can be found at https://chromium-try-flakes.appspot.com/all_flake_occurrences?key=ahVzfmNocm9taXVtLXRyeS1mbGFrZXNyOAsSBUZsYWtlIi12aXJ0dWFsL2dwdS9mYXN0L2NhbnZhcy9jYW52YXMtY29tcG9zaXRlLmh0bWwM.

Flaky tests should be disabled within 30 minutes unless culprit CL is found and reverted. Please see more details here: https://sites.google.com/a/chromium.org/dev/developers/tree-sheriffs/sheriffing-bug-queues#triaging-auto-filed-flakiness-bugs

The test times out infrequently on the mac trybots. I don't think it's worth disabling the test as it usually passes by the second retry, but we should still investigate why the timeouts happen.

Detected 3 new flakes for test/step "virtual/gpu/fast/canvas/canvas-composite.html". To see the actual flakes, please visit https://chromium-try-flakes.appspot.com/all_flake_occurrences?key=ahVzfmNocm9taXVtLXRyeS1mbGFrZXNyOAsSBUZsYWtlIi12aXJ0dWFsL2dwdS9mYXN0L2NhbnZhcy9jYW52YXMtY29tcG9zaXRlLmh0bWwM. This message was posted automatically by the chromium-try-flakes app. Since flakiness is ongoing, the issue was moved back into Sheriff Bug Queue (unless already there).
According to 

https://bugs.chromium.org/p/chromium/issues/detail?id=845266#c3, 

you should mark it as flaky, and point to  bug #726075 

"Note that it's expected that, while switching from OSMesa to SwiftShader fixes many issues, it can introduce some flakiness in some tests at the beginning, but these issues should be ironed out as we fix these one by one. It is perfectly acceptable to add flaky tests to the TestExpectations file, pointing to  issue 726075 , and we will try to solve all these issues as soon as possible."
Status: WontFix (was: Available)
This has been so stable (after a period of huge flakiness) that I suspect this to be fixed and feel comfortable closing this for now.
