Steps to reproduce:

After enabling "dom.ipc.useNativeEventProcessing.content" I get very high CPU usage of the main process when video is playing. Probably this bug is also appearing in some other situations.

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Content Processes' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Component: Untriaged → DOM: Content Processes
Product: Firefox → Core

Well, don't enable it on Windows :)
Hopefully we could get it disabled on all the platforms.

Curious, was there some reason why you enabled that pref?

Elle Solomina, please see question on comment#2. Thank you.

Ok, I disable this option. Previously, I enable this option because performance is much better when CPU is fully loaded by another applications.
