Are you using SuspendLayout/ResumeLayout calls during the resizing?
It seems that many of these controls flicker a lot during painting/resizing/moving.
The SuspendLayout/ResumeLayout helps in some cases.

Hello JSW W.,

Could you send us the source of the control that flickers to reproduce the problem, because when we put a Browser in a user control and set this control as a Child of NUIDocument, the control behaves normally when is resized?
Thanks.
