Has the design of YouTube, Google translator and the search itself changed?

Question

Google

For many on YouTube, the design has changed a little, namely, the search bar has shifted to the center. For me, it only changes in incognito mode or after clearing the cache

. When I enter my account - it becomes normal.

In the steam browser in Google, the search bar has become rounded, but mine is normal.
On the phone, the design of the translator has changed dramatically (web version, not applications), on the computer, everything is the same.
