description

The image in the scroll view of wonderous doesn't consistently move up on a scroll gesture. In PRs that address the image loading problem the stutter seems worse at first, then seems to resolve itself, probably as a result of texture caching.

observed result

imagebounce.mov

expected result

I expect a smooth scroll where the image of the dresser move consistently upward. There may be stutters, but in this case it doesn't seem to be a stutter. The image seems to go up->down->up instead of up->stall->up
