Why is the scroll bar in Windows 10/11 so narrow? Reducing Clutter is MS Opinion

It also suggests that most mice have the option to scroll without the wheel. But this still fails. And Discord has a dark background with a THIN scroll bar, making the problem even harder.

"AI Overview Learn more If you find the scroll bar on Discord to be too thin, it's a common complaint as many users find the default scroll bar width in Discord to be quite narrow, making it difficult to click on precisely to scroll, and is considered by some as a design flaw within the platform; there's currently no direct setting within Discord to adjust the scroll bar thickness.

And for apps/websites that do show scrollbars, sometimes they are barely useable. ChatGPT is one example.
