Lag or delay with the blocks

For a while I have been playing and there is such a lag! Or maybe a delay in the world when you placr a block that does not appear, it remains hidden, or when it is broken, it remains to appear while it was originally broken or non-existent, in addition to planting, opening and closing doors, barrle , fences....etc, also when placing an item frame that does not It only appears after a while

Also, when blocks are broken, their item will slowly drop and then return to its normal speed
