Lumen/AA flickering

Hello everyone, how are you?
I’m having this “flicker” problem that happens in several of my scenes, in this case on the books.
I’ve already tried adjusting AA, Lumen, and other settings, but the issue doesn’t go away.
Does anyone have any idea how to fix this?
I’ve already tested some solutions from other users, but they didn’t solve the problem.

Thanks.

see if this helps in your chasing for fix

Might be z-fighting or moire, which can become more noticeable at lower resolution (if screen percentage is not 100%).

Can you confirm that there are not two or more faces occupying the same space?

Is screen percentage lower than 100??

Thks, The issue seems to be related to small areas or thin parallel lines, but I believe it is caused by TAA.
There are no overlapping meshes.

Thank you, I’ll watch the video and see if it helps me.

if you click video i posted i pasted it to timeline where it explains possible cause just around 42:20 or so
