I posted this already once before her, but did not get any answer:
On some pages, where tabs are used, especially on a page with nested tabs, the top items of the page are shown faded in the beginning.
Thex become clear, full color, when scrolling the page up.
This happens on PC and tablets, but not on a phone.

What must be changed ? Please help!
