:hiro, since you are the author of the regressor, bug 1571758, could you take a look? Also, could you set the severity field?

For more information, please visit auto_nag documentation.

This is probably a dup of bug 1782797, but I'd keep opening for now.

Interesting, it looks like bug 1782797, which I thought was Linux-specific. Does setting layers.gpu-process.enabled to true mitigate the issue? (on Linux it helps a bit for me, but causes stutters on gpu-intensive sites)

It seems to already be set to true for me.

I've also noticed that this issue occurs while scrolling long emails in Gmail.
