Looks like a combination of backing-sharing, transforms and overflow:hidden.

This is an Async Overflow Scrolling issue. Mac WK1, AppleWin and WinCairo don't have this issue because they don't use Async Overflow Scrolling. Disabling Async Overflow Scrolling Internal Feature setting of MiniBrowser can work around the issue.
