If you move a window, the windows below need to update themselves as 
quickly as possible. Especially in such cases the visual feedback may 
suffer, if multiplexing is done.

I totally agree that most windows do close to nothing almost all the 
time, but it's also on hot spots, when they must behave properly.

I'm a bit sceptical about being closefisted regarding window resources. 
I completely see the need for being economical with bitmaps, since the 
bitmap itself can be a cheap resource (only a bit of memory for small 
bitmaps), but a window is relatively dear on application side, anyway.
