Why did the endless cascading of windows (such as the ‘not responding’ window)on older operating systems occur?
Windows didn't cache a windows pixels when something is placed above it. It simply asked the message handler to render that area of the window when the area was returned to the window. When the message handler is unable to execute this it keeps the pixels that were last rendered.
The Short Answer
Windows didn't cache a windows pixels when something is placed above it. It simply asked the message handler to render that area of the window when the area was returned to the window. When the message handler is unable to execute this it keeps the pixels that were last rendered. A message handler can fail to handle the message due to a number of problems. Generally messages are placed in a queue for the program to read and execute, if the program stops pulling these out and reading them then windows can guess that the program is misbehaving.
