Minecarts sometimes disappear when under water.

When I look on any minecart that is in water while I am outside the water, the minecarts disappear. But only when I look in certain directions(as I figured out, idk if it is true -> when I either look on the minecart or when the minecart is slightly to the side of my cursor or below the cursor) and it happens primarily with the last minecart that I placed and when I destroy the last placed minecart, it is happening with the previously last placed minecart.

And it disappears only sometimes.
