I recently switched to Firefox and have been frustrated that videos and streams stutter and drop frames drastically when not the active window. I enjoy having videos and streams open when gaming and this doesn't allow me to do that. Some fixes that I have tried are: widget.windows.window_occlusion_tracking.enabled to false layers.acceleration.force-enabled to true gfx.webrender.all set to true My specs: i9-10900KF RTX 3070 16GB 4266mhz Game in question is FFXIV in borderless fullscreen. I know that using exclusive fullscreen solves the issue, but I like being able to use my other monitor while playing.
