[Bug 1614050] Re: Window depth order messed up

[Brian Murray]

Hello dronus, or anyone else affected,

Accepted metacity into xenial-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/metacity/1:3.18.7-0ubuntu0.2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

** Description changed:

  # Test Case
  Described in comment https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1614050/comments/16
  
  # Impact
  Sometimes the window depth order is wrong, for example the desktop icons appear above all windows. Also sometimes windows disappear and the only way to bring them back to life is restarting Metacity. This can result in loss of work results for users who do not know how to deal with this bug.
  
  # Fix
  The Xenial fix is composed of two upstream commits, in gnome-3-18 branch:
  - https://git.gnome.org/browse/metacity/commit/?id=d5f9e42e30c67d07
  - https://git.gnome.org/browse/metacity/commit/?id=72488dc76ee24a3e
  
  # Regression Potential
  The patch has been in Yakkety for almost a month, and nobody complained.
+ [bdmurray] - That's not a description of what could go wrong, rather one of what hasn't gone wrong in Yakkety.  Please add some possible regressions and what users testing this fix should look out for.
  
  =============================================================================
  Using the gome-flashback session with metacity is totally messed up since I updated from Ubuntu 14.04.3 to 16.04.1.
  
  All the effects mentioned here do not appear when using compiz, so I
  guess Metacity is broken.
  
  -Windows that should open in front (like Kupfer) appear behind the
  windows already open.
  
  -Before nemo is run, the Ubuntu default desktop background image appear,
  it can't be changed by settings. I just guess this is due wrong ordering
  of the true background and some window used by Gnome for showing the
  selected background.
  
  -If nemo is run to take over the desktop, the destkop icons appear in
  front of all windows.
  
  I guess all those effects originate from a similiar reason. None of
  these problems where appearant at Ubuntu 14.04.
  
  This is a total show stopper for using metacity on 16.04 as everyday
  applications like nemo and Kupfer can't be used.

** Changed in: metacity (Ubuntu Xenial)
       Status: New => Fix Committed

** Tags added: verification-needed
