Comment 0 for bug 947025

Often when I try to maximise a window that is on the primary display it will move to the secondary display instead. Here is what I did just now:

I have a Chromium window that I want to move from the secondary display to the primary display, so I drag the window over to my primary display, and drag the title bar to the top of the screen.

Result: The window maximises, but on the secondary display instead.

Same scenario, but instead of dragging the window to the top I use the window controls to maximise the window.

Result: The window maximises, but on the secondary display instead.

Same scenario, but I try to maximise on half the primary display by dragging to the left (or right). I'm doing this just to test really.

Result: It works as expected and the window changes dimensions to fit in the left (or right) half of the primary display.

Workaround:
If, after dragging the window to my primary display, I resize the window to make sure that it fits fully w/in the dimensions of the primary display it will maximise on the primary display as expected. Therefore, I suspect the problem is that some part of the window is hanging off-screen and Compiz assumes I want to move the window to the other display. This is a poor assumption, and quite honestly very frustrating. My secondary display is quite a bit larger than the primary and this means this scenario happens frequently.
