I looked at your test case and it doesn't seem to work on windows 7. The screen is completely gray with no animation, UNLESS I click on the part where the main window should be. That seems to kick it off. However, clicking on the area where the child window should be doesn't do anything (the screen stays blank).
This actually makes sense, although unexpected. Windows 7 doesn't start drawing immediately for some reason. That's why you have to click. Some fiddling with the test case should probably fix that. That's irrelevant to the bug.
In WINE, the animation starts immediately, although there is a black rectangle in the top-left corner. However, when I click anywhere on the main window, the child window is sent to the background and then animation plays out on the whole screen. However, similar to the windows behavior, when I click on the child window, nothing happens (the child window continues to obscure the animation below).
This is expected. You do expect a window to come forward when you click it. Although this only happens in virtual desktop mode.
