How to Fix Scroll Lag on Heavy Javascript Sites
Patrick Bushe · May 1, 2026
Scroll lag on heavy web apps happens when the page's own code keeps the browser busy, and no extension can change that order of work. What helps: close other heavy tabs or turn on Memory Saver (Settings > Performance), turn off extensions you don't need, since many run on every page, keep graphics acceleration on, and open Chrome's Task Manager (Shift+Esc on Windows) to see which tab is using the most CPU.
