I have tried learning on clipping behavior of Windows 32 and found that the child windows are totally handled by another thread, which is causing this problem and one can solve this by enforcing WS_CLIPSIBLINGS, but I am not able to implement the same. How can I use WPF to solve this issue efficiently?

What is Reverse Painter’s algorithm? What problem or issue does this algorithm caters to? With just the name it is difficult to identify the area it is applied to but I have heard that it is related to Graphics? Can someone tell me how is it related to computer Graphics? Also I have heard about some flaws in this algorithm, and someone suggested about z-buffer solution, but I have no idea how both of these are related. Can someone please explain me this?

For a very very long time he has been doing this without any problems, but of late the computer has been very unstable and  its speed has also reduced.
