Vsync/Screen Tearing Issues

For the past couple months or so, I've had constant issues with screen tearing when scrolling or with 60FPS YouTube videos. Nothing I've tried has seemed to work, and it's seriously bugging me. The issue does not seem to be present when the video display is small, but it's apparent as ever when fullscreened.

Things I've tried that I can remember, and that haven't worked: - Enabling hardware acceleration - Forcing VSync through NVIDIA Control Panel - Setting layers.acceleration.force-enabled in about:config to true
