Camera Raw v8.7.1 Adjustment Brush Problem

I’m using Adobe Bridge and my problem is in Adobe Camera Raw 8.7 and 8.7.1 itself. The Adjustment Brush cursor clicked position and the actual area that will be painted is not in the same area. As you can see the picture shown below, the actual painted area is being offset about one cm away from the cursor clicked position. Only the Adjustment Brush is affected. What's more, the cursor is larger than usual and the color changes to black instead of white. Hope someone can help to give a solution or hopefully Adobe can fix the problem.
