the scroll bar is too thick:

Are they actually different widths/? Or is the thumb just slightly less rounded?

When we initially moved to Controlsv2 the scrollbar was actually wider, but we should have forced it back to the typical width. If it's wider for you, then this might be the inverse of #13361

they actually has different widths. the thicker one is about double width of the normal one.

Really? That's weird. In your screenshots, the first is 22px, the second is 24px. That's weird that their different at all tbh.

What DPI scaling is your screen set to?

I'm using windows's snipping tool to create that screenshot, instead of prtsc key, maybe the image is compressed.

Sorry if the Chinese UI is confusing.

a comparison:

this is windows terminal's scroll bar

this is a normal one

the blue lines has the same widths.

I see the same thing in #13361 (comment). I bet it is also thicker than normal.

To add here, the scroll bar is normal in settings UI.

At fault is the WinUI scrollbar template, which works in a confusing way.
To customize the space around the thumb you need to change ScrollBarThumbStrokeThickness to 2x the expected padding.

In this case you want 5px, so you would set it to 10:

Unfortunately, this will also affect the thumb in minimal mode:

Normally you'd want to be able to set the width for each state, but it's not really possible currently.

I'll stick this on the backlog, but it's blocked on the upstream microsoft/microsoft-ui-xaml#7682.
