Bug Description

[IMPACT]

The Dash was rendered underneath fullscreen windows so it was invisible, although it grabs keyboard input.

[TEST CASE]

- Launch an application in fullscreen (Firefox, Totem).
- Hit the Super key to call the dash.
- The Dash should appear.
- Keyboard input should be directed to the Dash.
- Clicking anywhere on the full screen application should close the Dash.

[REGRESSION POTENTIAL]

No known regression potential.

[OTHER INFO]

The fix for Ubuntu 14.04 LTS was cherry picked from the Ubuntu "Vivid Vervet" dev release where it has been in production use for some time without apparent regression.

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.

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.

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.

Daniel van Vugt (vanvugt) wrote :

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.

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!
