Letters in the Google Chrome browser of different thicknesses. How to change them?

Question

Fonts

Hello. Bought a new laptop. Everything works fine. But in the Google Chrome browser, for some reason, the letters are of different thicknesses. That is, the same letter, for example U. It can be of different sizes. That is, the middle and bottom crossbars of the letters are thick, and the outer ones are thin. I tried to somehow adjust the font - it does not work. Please tell me what should be done? Only, if possible, in simple words. Thank you.
