Sometimes when i press the button to bring up the menu to enable and disable blocks to be viewed. The game will freeze and will do so until the game is restarted.
I have no issues with toggling the xray on and of, however every 1 in 3 chance the game can freeze with the menu.
it maybe a bug freeze when having an activated block or when pressed to fast.

i love your mod as it makes mining much more enjoyable and the amount of time mining is reduced allowing me time to build houses and that.

i'm actually having the same issue and it sometimes just works and other times freezes idk why

Same here, it's frustrating at times

Lower your distance. This is due to poor optimisations in 1.16 but I won't be going back to fix it as I don't support that MC version anymore. PR's are welcome.
