Bug Description

[ Impact ]

A maximized application's title bar does not merge into the menu bar once a user has performed Super + W (window slide). Note that if one does not do Super+E, then the bars to merge together. However, once Super+E has been performed, this bug persists for the lifetime of the windowed application. If the application is restarted after doing Super+E, then the bug is gone. Thus, it seems like Super+E introduces this bug for the lifetime of the windowed application.

Expected behavior: Maximized window's title bar is merged into menu bar.
Observed: Does not occur after Super+W is performed.

[ Test Case ]

(1) Open one or more Terminals, place one in maximized mode (eg. by using control-super-up or clicking the embiggen button).
(2) use super-W to enter the spread mode
(3) select the maximized terminal window
(4) lookee lookee, separate title bars without the fix!

[ Regression Potential ]

Any change to the Unity desktop shell could potentially introduce a new crash or hangup.

[ Additional Info ]

The Unity SRU fix for Ubuntu 14.04 LTS was cherry-picked from upstream Unity where it has been a part of the Ubuntu "Vivid Vervet" dev release for some time now and has demonstrated no regressions.

I noticed that this does not effect google-chrome. Though, that might have more to do with the fact that google-chrome doesn't have a proper title bar...

So, this actually kinda worked itself out. After rebooting my computer, I no longer have this maximization problem.

I can confirm this behaviour on a fresh install of 14.04 - although "Window Spread" doesn't seem to trigger it in my setup. It seems to just happen at certain points, and closing the window and reopening solves the issue temporarily.

On my Ubuntu 14.04 setup I am definitely seeing an interaction between using the spread function and whether windows maximize correctly or not.

However, it is slightly different from the OP.

It very often happens that a window shows the incorrect behaviour (i.e. maximizing does NOT merge its menubar with the main menubar). If I then activate spread, and then select THAT misbehaving window, it will maximize correctly. After this, other windows then show correct or incorrect behaviour, but I've not been able to find a pattern in that.

Same thing here. The important thing to consider to reproduce the bug is to use the Keyboard only. When I select my windows in spread mode with the mouse, there is no problem at all.

The problem comes only when I use the "type to select" new feature. The selected windows is ok, but all the other are not maximized correctly anymore (but it can be seen only with Alt-Tab, if I use the mouse OR the "type to select" feature, the new windows selected is ok).

I git the same problem. It behaves exactly as #6 describes. Using Super+W again and select the bugging application makes the title bar merge with the top bar as intented.

Bruno Nova (brunonova) wrote :

Same problem here.

I have seen the same behavior described in #7.
The title bar problem occurs when I use spread (Super+W), type something until only 1 window appears, and select it (using either keyboard or mouse).
This breaks the title bar integration with the top panel for all windows (even those not maximized, visible when I then try to maximize them) EXCEPT for the window that I selected in spread mode.

This happens with both global menu and locally integrated menus.

The fix is easy for me, though. Just open the spread mode (Super+W) and select any window or press Escape, and the problem is fixed for all windows.

Also, I've seen the title in the top bar sometimes appear below the close/minimize/maximize (with locally integrated menus, at least) after using the spread mode. But it's not very consistent (and it's probably a different bug).

I have the same issue. First it was with Google Chrome, but today it happened with skype window.

Its solved when I do `super + w` on problem window.

I'm still having this issue in Utopic 14.10, Unity 7.3.1

The only fix I've found is deactivating Spread in Unity Tweaks.

Comments #7 and #9 are describing a different bug related to using keyboard on window spread:

This bug occurs for me when I disabled and re-enabled window spread in Unity Tweak Tool. I could solve the problem in a strange way:
1. selected Restore Settings of window spread on Unity Tweak Tool;
2. disabled and re-enabled the window spread on Unity Tweak Tool;
Suddenly Ubuntu Unity Plugin got disabled and I lost window decorations and indicators.
3. I opened a Terminal, enter `ccsm` to open CompizConfig Settings Manager;
4. noticed "Gnome Compatibility" and "Window Decorations" are enabled, both of which conflict with Unity Plugin;
5. enabled Unity Plugin and resolve conflicts with those two.

Now I can use window spread without problem except the type-to-search which I've described in lp: 1386714.

I've tested the trusty-proposed update in a VirtualBox virtual machine (version 7.2.4+14.04.20141217-0ubuntu1).

The update fixes the issue.
Now when I press Super+W, type something until only 1 window is shown (filter) and select the window, the title bars of all of the maximized windows are correctly merged with the top bar.
It also works when the windows are spread through multiple workspaces and I use Super+Shift+W to view all of the windows.
And it works both with the global menu and with locally integrated menus.
