           Summary: Page flickers a lot, when page gets big
           Product: WebKit
           Version: Safari 15
          Hardware: iPhone / iPad
                OS: iOS 15
            Status: NEW
          Severity: Critical
          Priority: P2

          Assignee: webkit-unassigned at lists.webkit.org

Scrolling and showing content was running smooth with this css on parent div before iOS 15.5:

-webkit-backface-visibility: hidden !important;
-webkit-transform: translate3d(0, 0, 0) !important;

But now it flickers a lot, when the page gets big.

Images are object URLs created with createObjectURL

See this video, about 60 images on the page (Was no problem before)
