+ The Petzold 95 contains an example program, scramble, which divides the
+ screen into small rectangles, swaps them randomly., and then waps them in the
+ exact reverse order so that in the end the screen is unchanged.
+    The first time I ran it in Wine I was actually amazed that it managed to grab
+ the screen's contents at all.
+    But I quickly recovered and started wondering why the screen is not restored
+ correctly. As the program runs the contents of the cells quickly become slightly
+ corrupted and they end up looking all alike.
+    And the screen is scrambled until you invoke the refresh of your window
+ manager.
+ 
+    Actually, I still wonder why it does not work hence this report!
+ 
+    Oh, I did try to make sure noone was updating the screen while this
+ application was running.

+ 
+     Is there some fundamental impossibility, in which case fine, let's document
+ it somewhere and close this report. Or is there an actual bug?
