Thank you all for your answers.

According to what you all suggested above, I think the most possible problem is
caused by interface between raindrop nether surface and leaf upper surface. The
result image attached above is generated in the situation that the raindrop
nether surface is lower than the leaf upper surface, that is to say, the leaf
surface traverses the raindrop body.

What I want to ask now is that when the two objects (raindrop and leaf) have the
exact coincident interface (between raindrop nether surface and leaf upper
surface), which surface should be upper? The raindrop nether surface is upper or
lower than leaf upper surface?

Considering the fact, the raindrop is on the leaf surface, therefore I believe
the raindrop nether surface is upper than the leaf upper surface, am I
right？

Thank you!
