Firefox stops responding to scroll events from my trackpad. When this happens randomly, it affects all tabs including new or reloaded tabs.

I first saw this bug about a week ago and I've seen it about four times since then.

I have the following extensions installed:

You mean wheel events?

Is this with or without e10s?
Yes, I meant mouse wheel events.

I'm using Nightly 48 with e10s. I will test without e10s, but the problem is so intermittent that I will only be able to confirm that the problem happens without e10s if it actually happens.

Kats, could this problem be related to any APZ changes that have landed over the past week?
