Why
When
<View />is non-fullscreen, the calculation of isOffscreen doesn't consider the position of left and top.I made a demo here. You can see the bottom boxes disappear suddenly when you scrolling before it's not fully outside the canvas.
What
The checking should use the canvas bounding box rather than only width and height (it assumes position at top left corner from the screen).
