Why is the font in the popup cloudy in Chrome, but the same element in the flow has a clear outline?

Question

css

Good afternoon Colleagues.
Please help to catch the bug:
SUBJECT
There is such a landing page diavita-promo.com/webinar/es
It has 3 forms. Two in the visible document stream, one in the popup window.
PROBLEM
Forms are laid out the same way. KSS is the same.
Font form-popup - muddy! do anything with it.
Antialiasing is worth it. Gayscale - worth it. The bug only appears in Chrome!

Thank you in advance for your response!

Come up with a way of positioning without transformations.
