Public bug reported:
Compiz has very strange and inconsistent behaviour when it comes to
corner or "edge resizing" in Ubuntu, i.e. dragging a window to one size
of the screen (or, if enabled, a corner).
Expected edge behaviour:
1. Drag window to edge of screen.
2. Window resizes to fill up that half of the desktop.
3. Double-click window title bar to maximize window.
4. Double-click window title bar again to restore window.
5. Window restores back to fill one-half of the desktop.
Recorded edge behaviour:
1 - 4 as expected
5. Window restores to position it was in before it was ever edge-resized.
Expected corner behaviour:
1. Drag window to corner of screen.
2. Window resizes to fill up that quarter of the desktop.
3. Double-click window title bar to maximize window.
4. Double-click window title bar again to restore window.
5. Window restores back to fill one-quarter of the desktop.
Recorded corner behaviour:
1 - 4 as expected.
5. Window restores back to correct corner of the desktop, but with a large
"gap" between its top edge and the Unity top bar.
OF NOTE: The above corner behaviour only occurs in the top corner. The
bottom corner restores the window as expected.
As we can see, even the incorrect behaviour of the edge and corner
resizing is inconsistent. They're both incorrect, but in different ways.
