Choppy video playback on most sites
Hi, I've been having trouble playing video on most sites, including YouTube, Reddit and Instagram - yet, strangely, not when I'm streaming, like on BBC iPlayer. While my internet connection is decent, YT goes as far down as to 360p to keep the choppiness away.
I've tried changing settings in about:config, and toggled hardware acceleration on and off; it gets even worse when it's off. Turning off extensions like uBlock Origin and Control Panel for YouTube also didn't help.
Any ideas? I'm on the latest Nightly PC build, but the problem's been occurring in earlier versions as well.
