We've seen it a lot in the Flash Player, though it only happens with fairly convoluted screens, we can't get a small enough project showing the issue to send to Adobe.
We've noticed it doesn't happen in AIR.
I also have a very simple screen with just 3 drop downs and 7 radio button which show the same behaviour. Though due to security reasons I cannot post that screen over here. I work on a virtual machine and I do not see this problem happening for me, but our clients work on normal PCs and they see it every time they scroll the screen.
So does that mean that there does not exist any solution for this problem? I cannot move to AIR at this time.
We've certainly not found a solution.
If you can re-produce it with a small test app, add it to the bug jira, and lets see if Adobe can fix it.
I encountered a similar situation and fixed the issue by setting fixed height and wdith for all the components in the container . You could try that
