I can't replicate the problem.
Can you provide a .blend file showing the issue?

Some objects in the scene will cause such problem. After deleting them, the 3d cursor grid snap back to normal. If ctrl-z to add them back, the weird snapping would appear again.

The problem is that the target is set for the active element.
It is as if the pivot of the cursor were the active element center.
So this center is snapping to grid.

This is more a matter of design than a bug.
