When my character crouches/sneaks, the first-person camera drops further than what it should thus causing the reticle to not select the block I wish to interact with. I would have the reticle over a block right in front of me, but when I mine, the block BEHIND the one I'm aiming at gets destroyed instead. It's especially annoying when I'm trying to place blocks.

In the following image, my character is crouched. The issue is not present when my character is standing upright. I can confirm the reticle is in the direct center of the screen.
