ScrollPane caching optimization was disabled due to a bug reported in RT-39755. It was evaluated to be too complex and risky to fix for 8u60. This optimization was effectively disabled for vertical scrolling prior to 8u40, because of RT-35783 which obscured the bug.
Our investigation has narrowed down the bug to around pre-culling logic where dirty region is used:
