Tested mod version: DynamicTrees-1.20.1-1.3.0-BETA12.jar

To Reproduce

1. Generate a world with Dynamic Trees
2. Load in
3. Look at the weird leaves

Mods List
Doesn't matter, happens with only this mod installed too

Here are two videos for comparison (1.20.1 and 1.12.2)
1.20.1
1.12.2

I'm not sure what the extent of this is as I haven't seen the video, maybe it is doing it more than it should. However please note it has been normal in all versions for the leaves to appear and vanish from time to time, as the growth matures and underlying mechanisms cycle somewhat due to the way they work. This is usually not visible unless on an amplified random tick speed, however.
