Sorry for typo: "before user gets chance to hold on it"

As a contrast: on windows 10, the right-side vertical scroll bar always shows, and the length of scroll handle is much longer, which is better for UX

I believe we try to match Mac platform conventions so if the issue is that there's a timeout that feels to short, that's unfortunately not something that we control.

If there's a bug where we differ in behavior from native Mac apps or Safari, that's something we can look into. I'll put this on myself for now to take a look when I get to a Mac.

But i have found that on Windows the scrollbar will always show, but on Mac
platform, i must first initiate a fast scroll gesture to show it up.

This is unreasonable.

There is still a problem i noticed: seems current platform UI guides assume
different OS should adapt different UX.
But in real world, i have a Win10 notebook, & i also have a MAC, & i also
use a Ubuntu Linux workstation!

Chrome should adapt to a consistent UI style, no matter which OS it runs on.

No, in general, apps adapt to the platform conventions on which they're running. Chrome is no exception.

If you don't want disappearing scrollbars, Mac has a system setting you can set to "always show scrollbars" which should give you Windows-like scrollbar behavior: http://heresthethingblog.com/2015/03/10/mac-tip-macs-scroll-bars/

Ok, so taking a closer look, there does seem to be a bug in Chrome's overlay scrollbars. To repro:

1) Open any scrollable page, I used www.reddit.com
2) Scroll to show the overlay scrollbar
3) Move mouse over scrollbar, this causes it to expand
4) Leave the mouse still over the scrollbar

What should happen:
In Safari and other Mac apps, the scrollbar remains expanded and visible while the mouse is over it

What does happen:
In Chrome, the scrollbar disappears even if the mouse is over it. Moving the mouse continually keeps it shown but leaving it still doesn't. Ditto if the user clicks and drags the thumb: the scrollbar remains visible while dragging but if the mouse remains still (yet pressed down) the scrollbar will fade out.
