Intersect point of tangent of two circles seems detached
I'm using GeoGebra 5.0.372 on Windows 10 and encountered an issue when move circles around. One intersect point of tangent with circle seems detached (not move accordingly) when I drag the circle. The following figure shows the issue. Initially, Point F is the intersect of tangent line i and circle d. Is that kind of bug? Is there a way to solve it? Thanks in advance.
