      Description

      The code that attempts to copy parts of a Node's cache to minimize repaints for horizontal and vertically scrolled panes did not work on pixel-scaled hardware due to an assumption built in to the code. For now, this code was disabled in the impl_scrollCacheCapable() method if any screen is more than 72DPI, but with proper support in the cache-copying code, this restriction could be removed and scrolling optimizations restored on Retina-screened macs.
