Old UI, also in incognito mode

New UI when logged in, font is disorienting and ui is too white and sharp, its hurts my eyes.

I already tried every theme from appearance section still no success so far ,

How do i revert to the old one?

Thanks

Check your browser extensions. One of them might be overwritting your github theme preferences.

I tired on clean chrome install without any extensions but theme only changes when logged in. definitely UI changes is related to the github account.

Install Stylish. Make custom CSS file.
