Hold up, what befell the overlay scrollbars? After the update, they look "typical" (default windows scrollbars). This isn't OK, there is no compelling reason to have scrollbars constantly unmistakable, we have mouse wheels for looking over. Additionally, the default ones look too appalling.
Could you in any event empower scrollbar from show://settings for everything? It's a little scrollbar, sort of "imperceptible", would be a decent trade off.
