I am facing a strange issue with screen scrolling on 9810 device and simulator.

I am facing a strange issue with screen scrolling on 9810 device and simulator.
I have a complete order screen, which is shown when the order of the user is confirmed.

At the top there is Vertical Field Manager which contains another VerticalFieldManager ( containing Label Fields and buttonFields ) and a FlowFieldManager (containing images).
Now the problem that i am facing is that whenever i scroll the screen up and down , there are many gray lines appearing on the screen. It seems as if there is some screen refresh issue with the device. I tested on previous OS (4.5, 4.5 4.7 5.0) version, everything is working just fine on them. The problem is arising on OS version above 6.0 .

    I am very sorry for the late reply. However i fixed the issue by myself. I just overrided the paintBackground method in my class and inside that i wrote graphics.clear(). This seems to fix this scrolling issue. I will try Michael method too though.
