HD video playing on second monitor causing first monitor to lag when scrolling @2K
Lately when I've been playing HD video on my second monitor I've been getting laggy/stuttery scrolling on my primary monitor. The issue resolves itself once the video is done or I switch to a different tab, thus concealing the video. I'm convinced it's an issue exclusive to Firefox as I do not have the issue on Chrome/Edge etc, and my hardware is more than sufficient to keep up with the demand.
Current settings: Firefox 58.0b11 64bit, Windows 10 1709 Hardware Acceleration enabled Content process limit: 4 (default)
PC Specs: CPU: AMD Ryzen 5 1600 GPU: Gigabyte GTX1080 RAM: 16gb Corsair Vengeance LPX @2666MHz Monitor: 2x Asus 23.8" @1440p 60Hz
Thank you all for your time.

I would experiment with disabling hardware acceleration on both devices to see if there is a lag. AMD drivers may have is disabled, check about:support, that should give some information about the hardware, depending which window the firefox browser is open in, I think (sorry I do not have a monitor to test this)
