I know there are quite a few fixes for this. I've tried disabling all my extensions. Have had other people try it as well. Have even opened a new game with no map or tokens or anything and had people with far better computers than I. Constant map scroll lag. The scroll for options will work fine. But the map scroll is constantly lagging. Have cleared cache. But other people have encountered issues as well. A week and a half ago. No lag, but starting this past weekend on Sunday. Constant lag. Even on maps without tokens and such.
