Shadow streaks / lines on all settings except Low and Ultra

Hello all,

I’ve noticed that certain surfaces have some sort of shadow lines / streaks on them on all settings except Low and Ultra.
To better explain the issue, I’ve captured 3 screenshots.
Notice how the vertical lines / streaks are present on the stairs only on the medium setting while they are not present on Low and Ultra setting.
