Talos has detected a Firefox performance regression from push:

https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=d12bb5576d0f1ce9e24ff42dd567c337431504a3&tochange=cd0c67b9aeddba87b444752885396697da387620

As author of one of the patches included in that push, we need your help to address this regression.

Regressions:

2% sessionrestore linux64-pgo-qr opt e10s stylo 982.88 -> 1,006.50
2% ts_paint_webext linux64-pgo-qr opt e10s stylo 845.21 -> 865.17
2% ts_paint linux64-pgo-qr opt e10s stylo 844.25 -> 862.17
2% startup_about_home_paint linux64-pgo-qr opt e10s stylo 1,198.08 -> 1,222.33

This is most likely another manifestation of bug 1528332 just like bug 1530951 and 1527829. Since, we're not shipping on Linux I'm just going to dup it against bug 1528332

Yup, I agree with Jeff's conclusion above.
