[Bug 1004371] [NEW] "smart" window placement puts windows on top of each other while there is plenty of space


You have been subscribed to a public bug:

Consider the following program that opens 5 small windows:

  import cv2
  import numpy as np
  for i in range(5):
      cv2.imshow(str(i), np.random.random_integers(0,255,(64,128,3)).astype(np.uint8))

(needs python-opencv and python-numpy)

When I run it, all 5 windows appear exactly on top of each other. My
desktop is stretched over two monitors. Left monitor has nothing on it,
right one has emacs not maximized, the 5 windows pop up on top left of
the left screen.

I expect that the windows would appear in a way that they do not
overlap, since there is plenty of space on both screens for that.
