I was testing a new Intel 268v based Windows 11 laptop and scrolling feels a bit jank-y when using it on battery. Based on Task Manager Edge uses 'above normal' priority for couple of processes, I assume one of those is their GPU process. FF doesn't. When tweaking FF's GPU process priority manually using Task Manager, scrolling/panning becomes very smooth.
