:emilio, since you are the author of the regressor, bug 1661147, could you take a look?

For more information, please visit auto_nag documentation.

Seems like a clip not getting applied consistently, but somehow only while async-scrolling? I think this probably is a WebRender bug given that... Glen maybe you can take a look? I'm a bit swamped right now but if you can't please redirect the ni? back and I can take a look. Thanks!

Unlikely I'll have time to look at it any time soon, but I can put it on my list for now, anyway. Emilio, if / when you get a chance to look at it, feel free to reassign.

I believe bug 1799216 fixes this as well.
