:dolske - I wonder if this is related to bug 1600175, caused by the change in the window management system when Unity was dropped for GNOME3 in ubuntu1804. I am seeing this test fail consistently in the ubuntu1804 image. Could you please redirect the ni to someone who may be able to take a look and comment, thanks!

Flags: needinfo?(dolske)

I was able to fix this issue by installing compiz on the ubuntu1804 docker image and changing how pulseaudio was initialized in the test-linux.sh script. Putting this bug on hold, and if the changes outlined in the previous sentence do not break anything else, I will close this bug as invalid.

This test indeed passed as expected with compiz installed in the test image, but given that compiz is not installed by default on ubuntu1804 and wanting to ensure that we test in the closest possible environment for end users, this bug still needs attention.

Knowing that having only the window manager (which removes the top bar, dock, and other elements of a full desktop environment) should help with the fixing of this test. The expected migration date to ubuntu1804 is end of December.

Tracy - on searchfox I found you worked on bulk of the test. Do you have time to take a look at the failure, or pass on the ni to someone else who may know about this test? I suspect it is the presence of additional UI elements from the full desktop environment which is interfering with the test.

I touched this with guidance from Jim Mathies. I really couldn't help here. You probably want the author of the test case, Kris Maglione.

Thanks for the ni redirect Tracy.

The expected migration completion to ubuntu1804 is end of December 2019. Kris, would you be able to take a look? Perhaps the test should be marked with either a fail-if or skip-if for ubuntu1804 only? This is currently a permafail on ubuntu1804 mochitest-browser-chrome.

To push to try with ubuntu1804, use ./mach try fuzzy --ubuntu-bionic and select test-linux64 jobs as normal.

I do feel uneasy marking this as permafail, since there is another window-manager related failure (in that case, maximizing) so I suspect the tests should ideally be updated to reflect the changes in desktop environment from ubuntu1604 to ubuntu1804.

But alas, the migration to ubuntu1804 needs to proceed.
