(In reply to Matt Woodrow (:mattwoodrow) from comment #2) > We scroll the sticky layer (0x14290c800), and it appears that the resulting clip also scrolls. The layer has a scrolled-clip, but that has a y value of -255, so it seems that we're scrolling the clip from the metrics, which is not what I'd expect. Ok, I refreshed myself on the various types of clips on layers and scroll metadata, and I agree, the clip from the scroll metadata should be scrolled. It's not immediately clear from code inspection what is scrolling the clip here.
