I'm not sure I understand the issue. Your A and B scenario are the same, but you have different zoom levels listed as the result. Did you mean for scenario B to be be force-device-scale-factor=1.25? If that's the case then those numbers look correct to me. If scaling is set to 125% then the top chrome will be 125% larger and the text will 125% larger, which is correct.

Keep in mind force-device-scale-factor is a debug flag and we generally don't prioritize fixes to it.

If you have specific issues with Chrome being ugly or not pixel perfect at 125% then filing a bug about that would be very helpful, especially if you include a screenshot. Also note that Chrome is supposed to be larger at 125% scaling, that itself is not a bug.

Fix typo:

{B}
3. set Google Chrome DSF as <<<1.25>>> (by force-device-scale-factor)
4. open Google Chrome

----------------------------------------

I don't mean the `force-device-scale-factor` flag, the flag behavior is
proper now.

I mean the UI design.

Always know laptop's monitor is small.

1.25 DSF: chrome is too big, use too much room
1.0 DSF: text is too small, hurt eyes

Again, the text being that size is not a bug. Your "expect" screenshot has text that is too large, assuming your font sizes haven't been changed (which you can do via Control Panel>Appearance and Personalization>Display>Change only the text size).

The find text being blurry is tracked in  bug 666357 . The bubble arrow is tracked in  bug 624526 . The menu line is tracked in  bug 703209 . The omnibox right border wasn't tracked, but I know what the issue is so I left a comment in bug 668278. The permission selection border is new to me, but since we're in the process of removing it I won't file a bug for it.

Thank you for your report! I'm closing this in favor of the more specific bugs.

This thread is not a bug report, is a feature request for improve user experience on small screen.

Thanks your reply.

Whilst this might not be a "bug" it was displayed a certain way for a very long time (since I started using Chrome from like v10) then suddenly changed to very big.

1920x1080 @125DPI on a 22inch screen is considered small? I think not.

Normal scaling the bookmark bar + menus after this update make everything very big.
