Public bug reported:
Before we start: I'm not a developer, so forgive me if I don't get some
terminology right.
Alt+` window switching seems to change the order of windows in the
stack, while scrollwheel window switching does NOT. This results in some
inconsistent window behavior. I'm gonna try to illustrate the issue with
an example.
Open 1 Firefox window (let's call it F1) and 2 Nautilus windows (N1 &
N2). Keep all 3 windows unmaximized with a part of all 3 visible at the
same time.
Alt+` test:
1. Set the starting window order by clicking them in the order N1, F1, N2.
2. Press Alt+` once. The visible window order (from bottom to top) changes to
F1, N2, N1.
3. Press Alt+` again. The visible window order changes to F1, N1, N2.
Scrolling test:
1. Set the same starting window order as before by clicking them in the order
N1, F1, N2.
2. Scroll once over Nautilus launcher icon. The visible window order changes to
N2, F1, N1.
3. Scroll again over Nautilus launcher icon. The visible window order changes
to N1, F1, N2.
Notice the difference?
- Alt+` brings N1 and N2 together. This is the expected behavior.
- Scrolling leaves F1 between N1 and N2. This is okay if all windows are
maximized, but can be disconcerting at other times because you see unexpected
window movements.
