If anyone can help me I would be very grateful

I suppose I have a similiar one, but it usually happens when I exit inventory or smth, would be grateful for help as well)
You settings seems off though, could you share them? Graphics ones I mean

Everything is as low as possible without amd fsr2. But with the resolution scale 0.6
My PC settings are:
8gb ram
i5 10th
without graphics card

HITMAN game is pretty demanding to hardware specs, so I guess this is the problem.

To process all the graphics hardware should have at least the lamest supported graphics card.
Biult-in graphics cards could handle the task though, but because of their nature they can’t work with complex graphics which is mainly games of course.
They can display desktop or video, but when it comes to games, they are just not designed to work with such massive data and that’s why you are experiencing this issue.
You just need to upgrade your system or get a new, modern one, preferably which is built for gaming
