Test c212 from dom/canvas/test/test_canvas.html is failing on windows. Attached is a standalone page that demonstrates the problem. The gradient is supposed to go from yellow to blue but on Windows with WR enabled it goes from white to blue.
I can reproduce this on my Windows machine.

Hm actually it renders white -> blue for me even with WR disabled on my Windows machine. Weird.

Batch updating status flags based on WR schedule - please adjust if needed.
status-firefox60:
--- → wontfix
status-firefox61:
--- → wontfix
status-firefox62:
--- → fix-optional

On a clean local m-c build with WR disabled, running the test_canvas.html mochitest fails the exact same cases for me (canvas #c212). So maybe it's passing in automation because it's running on virtual instances, and because we're running QR on virtual-gpu instances, it's failing there? That would explain why it's failing for me locally as well.

So in production we're broken the same way as vanilla gecko? Sounds like it can be deprioritized..?

Let's move it to canvas2d since it's not WR specific. Still a real bug that should be fixed.

The attached testcase works as expected with gpu-canvas enabled on Windows.
No longer blocks: stage-wr-backlog, webrender-mochitests
Depends on: gpu-canvas
