When Waving Leaves (not Waving Foliage, somewhat confusingly) is enabled, vines will occasionally clip into the blocks they're placed on as part of their animation. See below for a still frame of vines clipping into a tree they're attached to.
A solution could be to make vines affixed to (solid) blocks not wave at all.
