[Cosmin Sabou [:CosminS]]

So far first time it failed is here. Sotaro, could the failures here have anything to do with the changes in Bug 1736479?

(In reply to Cosmin Sabou [:CosminS] from comment #3)

So far first time it failed is here. Sotaro, could the failures here have anything to do with the changes in Bug 1736479?

SanityTest run only on Windows and the failures happened only on linux. Then the failures seemed not related to Bug 1736479.

Wouldn't be very surprised if this had something to do with bug 1739450. I'll take this and investigate.
