Is this  bug 538697 , but now on Linux as well?

10:36:10.810 21214 worker/3 virtual/threaded/printing/webgl-oversized-printing.html output stderr lines:

 Issue 836298  has been merged into this issue.

Still seeing virtual/layout_ng_experimental/printing/webgl-oversized-printing.html fail after r551378. I guess we need to add "Failure" as a possible result?

There's also  bug 829804 .

Though logs say:

12:52:50.797 5961 [863/5633] virtual/layout_ng_experimental/printing/webgl-oversized-printing.html failed unexpectedly (test timed out)

So "Timeout" should have covered it? Maybe third_party/WebKit/LayoutTests/FlagExpectations/enable-blink-features=LayoutNG is not the right expecations file? I don't know enough about layout tests.

It needs an entry in the regular TestExpectations file for virtual/layout_ng_experimental/printing/webgl-oversized-printing.html as well, I think.
