Dash called with super key above fullscreen app is not interactive or does not show up at all.

Status changed to 'Confirmed' because the bug affects multiple users.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug is caused by Unity's nux windows being stacked below the fullscreen window.

The bug remains in Unity 6.0 however 6.0 honours the stacking order much better, so you don't even see the dash in that version.

Wish to add an observation I originally added while reporting bug 1030693 (duplicate of this):

Keyboard navigation works, though. Press down arrow key to get to Calc or whatever desired icon shown in Dash results. Hitting Enter opens the app.

Week 32: Ubuntu 12.10 Quantal (Radeon, Intel, Nvidia) with ppa:unity-team/staging

Same issue observed, dash is opened in the background and not visible to the user.

Action:
#. Set a window to full screen. e.g. F11 in a web browser.
#. Verify you can scroll the window.
#. Tap the Super key.

One more, perhaps related observation.
Click on the Time/ Calendar indicator. Calendar is shown. Now if Chrome pop-up indication from Gmail arrives, though it is shown above the calendar, clicking on the Gmail notification has no effect. Calendar has to be dismissed first, only then.

One more, perhaps related observation.

1) Super key + W: shows all windows opened
OR
2) from Launcher, click on the icon of a program that has multiple windows open. shows the windows opened for selecting.

Under such circumstance, though the indicator bar is shown, it is inactive. Clicking with mouse, say on the date/ time or the cog-wheel for accessing system menu does not work. In contrast, icons in Launcher are shown, and can be clicked to open relevant program. This is inconsistent.

If a UI element is shown as clickable (not grayed out), it should work. Or else gray it out to set the expectation right.

3v1n0: Please note that this is a stacking issue. The unity shell painting order is correct and should not be changed.

The problem is that the shell is painted according to where the Nux input windows are in the stacking order. And the Nux windows aren't being raised fully, it seems.

Week 33 - Ubuntu Quantal 12.10 with ppa:timo-jyrinki/prerelease

Same issue observed, dash is opened in the background and not visible to the user when a window is open in full screen mode.

Week 35 - Same issue observed on Ubuntu quantal 12.10 with ppa:unity-team/release

Week 36 - Same issue observed on Ubuntu Precise 12.04 with ppa:unity-team/sru

Week 37 - Same issue observed on Ubuntu 12.10 quantal with ppa:unity-team/staging

Note: Bug 1055323 will probably need to be resolved first to make this fix reliable when "Unredirect Fullscreen Windows" is enabled.

Week 40 - Same issue observed on Ubuntu 12.10 Quantal ppa:unity-team/ppa

Week 42 - Same issue observed on Ubuntu 12.10 Quantal with ppa:unity-team/sru

A quick way to get unity back on top:

$ unity&disown

Week 50 - Same issue observed on Ubuntu 12.04 Precise with ppa:unity-team/sru

Added design to get a concrete answer on the expected behavior for overlay windows (dash/hud) when using a fullscreen app.

- Should the overlay be above the fullscreen app?
- Should the overlay not work when an app is fullscreen?
- Should we un-fullscreen apps when using an overlay?

Thanks!

@brandontschaefer; description updated to answer your questions

@John; Thanks!

I believe this action should be configurable - sometimes I don't want the Unity dash appearing, such as during a game.

The verification of the Stable Release Update for unity has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
