For a few days now when opening one of the tabs on feedly.com (see screenshot), the tab and content where flickering when opening it for the first time. Opening it again and it works fine, switching to another tab (flickering) and switching back, it flickers again.

1h in MozRegression gave me this Pushlog:
https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=ba66db7432e535f3eb80fd3d3586e64e96275ab3&tochange=f065bd870d0f16b1ae251add29eba05ab4742e24

Steps in mozregression:
1) about:config
2) gfx.webrender.all true
3) about:restartrequired => restart
4) https://feedly.com/ => login
5) get feed and open tab

Sounds similar to bug 1481313.

Additional flickering example of the three product images during loading and the tab throbber, which I guess both are related to bug 1477970. Thought it might be worth documenting just in case.

This should be fixed with Nightly build 20180921100113. Can you confirm?
