Title:
Ghost windows
Status in Unity:
Confirmed
Status in “unity” package in Ubuntu:
Confirmed
Bug description:
This happens at random times.
- Open several winidows of an application: for example, several terminal
windows, or several browser windows.
- In the launcher, N little white arrows appear on the left of the program's
launcher icon, where N is the number of open windows. This is correct.
- Click on those little arrows
Expected: the screen greys out and previews of the N open windows of
the program are shown, one nect to the other, all separate even if the
real windows are overlapped
Observed: randomly, sometimes works as expected; sometimes it only
shows M<N windows, and the others are not shown nor accessible in any
way. I haven't found ANY way to access that window, except closing all
the other windows of the same application. Then, when only one is left
(the "ghost" one), then it will become visible.
Please don't misassign the importance of this bug. This is huge.
I have only started observing it since the upgrade to 12.10, but I'm
not completely sure this is a regression. In 12.04, I used Avant
Window Navigator, because of the unusability of Unity without an
additional decent dock-like bar such as AWN. The upgrade to 12.10
uninstalled AWN without an apparent reason, so I've been using Unity
without it for a while. So the bug may have already been there.
