Just Tested this on the current DEV Build today. It's only partially resolved.
The option i used to test was: configure/game/general/adaptive croshairs: Disabled
Crosshairs still snap to ground. Example. I was trying to shoot an enemy laying on the ground in a road and my crosshairs went either above him or below him. he took over 200 rounds of saw because the crosshairs was snapping up and down on road.
Additional info:
Crosshairs might also snap to some "concrete objects" but its hard to tell if that's the culprit or the ground
I'm still hoping for complete control of crosshairs.
