1.16.100  is the worst update ever

First: the bugs of typing. Ex: you wanna type "One" but typing wrong to "Onr" and then when i delete letter "r" and type letter "e" it's become "Onre"

Second: Lagggggggs. World lag, new world also lag, sound lag, block lag, entity lag, i dont know why but there is a long delay after an action like breaking or placing a block, killing and entity or even when i walk, the sound come later than the action

Last, hope you fix these soon, thank you.
