The vanilla Minecraft crosshair is off-center. This resource pack fixes that issue and makes the crosshair a single pixel smaller, since the default is strangely large.
The default Minecraft crosshair texture is 15 by 15 pixels. The problem is that most monitor resolutions are made of even numbers of pixels. Trying to place a odd-numbered icon directly in the middle of an even-numbered screen leaves the crosshair off-center. (MC-157252)
