Fix GroundPolylinePrimitive

CesiumJS

Hello all!
I create a GroundPolylinePrimitive with the material type PolylineDash. When I move the camera, the lines start to move. How can I make my polyline static?

My code:

 let countyBorderPrimitive = new GroundPolylinePrimitive({
                    geometryInstances: new GeometryInstance({
                        geometry: new GroundPolylineGeometry({
                            positions: Cartesian3.fromDegreesArray(newBorPos),
                            width: 3,
                        })
                    }),
                    show: stores.groundStore.visibleStatus,
                    appearance: new PolylineMaterialAppearance({
                        material: Material.fromType('PolylineDash', {
                            color: Color.RED,
                            dashLength: 50,
                            dashPattern: 255
                        })
                    })
                });
                cesium.scene.groundPrimitives.add(countyBorderPrimitive);
