Falling blocks disappear for a split second when landing

在我游玩服务器时 出现了这个问题 我起初以为时服务器的性能问题 但后面我打开了单人模式 仍然出现了这个问题
且影响到的是所有会下落的实体方块（TNT除外，因为它不会在下落后替换为正常方块） I ran into this problem while playing on the server. At first, I thought it was a performance issue with the server, but later I opened single-player mode and the problem still appeared. It affects all falling block entities (except TNT, since it doesn't turn into a normal block after falling).
