This seems to be from Bug 1523969, Ryan can you take a look?

Blocks: 1523969
Flags: needinfo?(rhunt)

I'm not sure this is the fault of bug 1523969, that should have no functional changes. It only should've moved comments around.

I've double checked the patches relating to image/ and gfx/ which would be most relevant, and can't see any functional changes.

Flags: needinfo?(rhunt)

Jessie can you assign someone here please?

There are 17 total failures in the last 7 days on linux and osx.

Talked with Jessie, and I'll take a closer look.

Thank you Ryan.

Bug 1530928 landed shortly before the first failure.

Blocks: 1530928
Flags: needinfo?(sotaro.ikeda.g)

If Bug 1530928 triggered the failure. Bug 1534170 seems to related to the problem.

I added a logout to try test. The log said that the TextureClient was created in MediaEngineTabVideoSource::Draw(). The code was added by Bug 1440038. Bug 1534170 is going to address a bug related to Bug 1440038.
