Public bug reported:
To be honest I'm not sure how to provide extra details about this issue,
but it really is frustrating as sometimes it causes loss of unsaved
data. I'm willing to provide any required data, and debug the the issue
in any way I can if it helps.
The issue is always reproducible for me. Any window that is not
maximized, when in focus, disappears after pressing Ctrl+Alt.
It behaves as if it was moved to another "non-existing" workspace, so
the application would still be shown as open in the Unity Launcher. That
is, an empty arrow is shown next to the icon instead of a filled one. I
tried disabling workspaces with unity tweak tool since the shortcuts
unusable in state (They all contain Ctrl+Alt in them).
If the application that disappeared had only that one window opened, it
is possible to recover the lost window by clicking on its icon in the
launcher. But it doesn't work if you try to select from the list that
shows when pressing Alt+Tab (I think it's called the App switcher?)
The biggest problem, is when having multiple windows of the same
application opened. This makes it impossible to recover the lost window
unless all the other ones were closed first. (So I'd be able to open it
by clicking on its icon in the Launcher). Which is problematic as
sometimes i accidently use a shortcut that contains a Ctrl+Alt while I
have terminal windows running script or ssh etc. (The default shortcut
to open a terminal window is Ctrl+Alt+T which makes this even worse)
Steps to reproduce:
- Open a terminal window
- Open another terminal window
- Have any of the two terminal windows in focus
- Keep that window non-maximized
- Press Ctrl+Alt
- Window disappears
Notes:
- Ctrl+` cannot recover the window (Although the application switcher still
sees that there are 2 open windows of that app (It shows the 2 squares)
- Clicking on the terminal icon in the launcher only opens the second (and
still visible) terminal window
- Right clicking on the launcher icon does not list the hidden window.
- In some cases the application disappears completely from the App launcher as
well.
