Hi,

I leave you the regression range. It's been failing for a while now.

Best regards, Flor.

:Anca, since this bug is a regression, could you fill (if possible) the regressed_by field?

Happy to take a patch for 70, but since this is already triaged and set to P3 priority I'm setting it as fix-optional.
That will remove the bug from weekly regression triage.

Reproducible also on Nightly 71.0a1 on Ubuntu 16.04. (Build ID: 20190912094122).

I can also reproduce on Nightly with Ubuntu 19.04 but given that the configuration affected (Flash+Linux) is not a lot of our users, that it is a P3 with no assignee and the fact that it is not a widespread problem, I am going to mark it as wontfix for 70 (we won't take and uplift for this issue) and fix-optional for 71 (we would be happy to get it fixed during our nightly cycle if a patch materializes but we don't need to have this bug show up in our weekly regression triage queue).

I've tested in Ubuntu 18.04 - using latest nightly 71.0a1 - 16/10/2019 - same error for the games "Coral Isle" & "Golden Farm".
