"Always on top" breaks spread/expose

[Alistair Buxton]

Steps to reproduce:

1. Open three windows of one application, eg three gnome-terminal windows, by middle clicking the launcher icon three times.
2. Minimize all three windows.
3. Left click the unity launcher for gnome-terminal once. This should reveal a single terminal window.
4. Right click the terminal window title and click "always on top"
5. Minimize the terminal window.
6. Left click the unity launch of gnome-terminal once. The window you just marked "always on top" should unminimize.
7. Left click the launcher icon of gnome-terminal again.

What is supposed to happen:
All three terminal windows should be shown in spread/expose mode to allow you to select one of them.

What actually happens:
Nothing at all.

Additionally, raising those windows some other way (eg with alt-tab) sometimes leads to them displaying as empty black rectangles with window decorations.

confirmed, I don't get the black rectangles though

[Alistair Buxton (a-j-buxton)]

Black rectangles is an nvidia thing - it happens all the time with or without always on top, but this seems to make it worse.

[Cavia Porcellus (caviaporcellus)]

I think Alistair is correct: I have no Black rectangle issue (not using nvidia), but "always on top" is certainly broken in the way the OP described.
