When in creative when building I switch from block to block when switching from one block it will glitch back to the original block and makee place that the first block and ever since the new update placing blocks causes alot more lag then it would

2 glitches in one make it simple

When I am in the hotbar building in creative I will place a block and it works fine then I quickly switch to another block to place it and then it will glitch out and make me pla e the first block instead of the 2nd one also when building with blocks like using flying to build a row for a wall it causes alot of lag then it would before the new update
