I\'m using WindowChrome to restyle my window in an easy fast way but the problem is there is flickering when resizing the window, especially when resizing from left to right.
Your Problem is caused by the property NonClientFrameEdges which is set to NONE. This property Gets or sets a value that indicates which edges of the window frame are not owned by the client and At least one edge must belong to the client.
So change your code to:
NonClientFrameEdges="Right"
This will solve your problem.
