flickering of Facebook blue bar
With a newly installed Firefox Nightly (2018-03-31) I'm getting flickering of the Facebook blue bar when mousing around the page. See the attached video.
Summary: flicking of Facebook blue bar → flickering of Facebook blue bar
Perhaps relatedly, I get similar flickering in the Bitwarden popup panel.
The previous attempt to disable retained-dl just for the scrolled frame didn't work, since we might have already decided not to rebuild OOF frames within the scrolled frame at the point that we added to the dirty area. That results in the new list containing scrolled content, but not position:fixed content, and then the DAG no longer knows which is on top. It frequently gets it wrong, and things flicker.

Pushed by firstname.lastname@example.org: https://hg.mozilla.org/integration/mozilla-inbound/rev/0cb041700c38 Disable retained display lists when we have overlay scrollbars, as the z-index of the scrollbar changes between paints. r=mstange

I think bug 1450434 might be a dupe of this one.
The new patch in bug 1450360 should fix this.
Bug 1451971 was filed to track the ESPN issue.
Unfortunately, I could not reproduce the issue after several attempts on different builds (20180403100105; 20180403170332; 201804032200400) as well as Latest Nightly 61.0a1 by checking the Facebook bar, Bitwarden popup panel as well as following the STR provided in the duplicate bug 1450911. Cameron: Can you please re-check the Facebook bar on the latest Nightly 61.0a1 build and confirm back the results? Any feedback regarding the flickering of the extensions (as you mentioned Bitwarden) would be also much appreciated. Thank you.
These are both fine now, thanks.
