I noticed this with Dark Oak trees in specific and have not tested with other tree types.

Situation: Dark Oak trees planted on the border of a chunk (so that the 2x2 trunk will be completely in one chunk) where branches may cross the border into another chunk.

Effect: Sometimes the logs for branches that should grow in the neighboring chunk will not appear for several minutes after the tree has grown. I've completely cut down a few to have the tree logs appear up to 10 minutes after the rest the tree has been demolished. However, the foliage seems to grow normally across chunk lines.

While its possible this is related to MC-62166, I rather doubt it. Where invisible blocks placed can be hit these log blocks do not exist in the world until they decide to grow in.
