[Bug 1789356] Re: Dark purple (noise) background flashes up briefly during the login animation since Yaru was introduced

2018-11-13 Thread Daniel van Vugt
I found the problem yesterday.

The regression is that the gradient (which didn't appear at all before)
now only occupies the middle 50% of the screen. This means it looks
squashed and different to the login screen. The top and bottom 25% of
the screen are solid colours.

It looks like a problem with texture coordinates and GL clamp-to-edge,
since the gradient is really only a 1x2 two pixel texture rendered with
linear filtering.

** Tags added: regression-release

** Summary changed:

- Dark purple (noise) background flashes up briefly during the login animation 
since Yaru was introduced
+ The wrong background flashes up briefly during the login animation since Yaru 
was introduced

** Description changed:

  [Impact]
  
- Dark purple (noise) background flashes up briefly (for a split second) during 
the login animation.
+ The wrong background flashes up briefly (for a split second) during the login 
animation.
  The login screen and gnome-shell's system background are meant to be the same 
image so that the login procedure can VT switch without the user noticing. Then 
the final desktop expands over the system background. However it appears the 
login background and system background are not the same image any more, causing 
a visible glitch during login.
  
  [Test Case]
  
  1. Install new version, logout
  2. Log in into GDM
  -> Check that at login startup, the background matches GDM ones (same color, 
same gradient)
  3. Logout, install gnome-session
  4. Reboot so that GDM takes gnome-session into account
  5. Select GNOME session and login
  -> At login startup, the background will matche the GNOME default one (from 
the lockscreen: grey noise), which matches GDM one if reset to default GNOME 
via update-alternatives.
  
  [Regression Potential]
  
  This code is loaded at session startup, if there is a syntax error, the 
session wouldn't start at all.
  This has been of course tested before committed (both on ubuntu and GNOME 
sessions)

I was wrong. I can see the same bug in git builds. It's just not obvious
when you're not coming from the login screen.

Thanks. I have confirmed on a third cosmic machine the same bug in
3.30.1-2ubuntu1.18.10.1 :(

However, when I apply the above patch to gnome-shell git (either master
or gnome-3-30 branches), there is no bug at all. The patch works fine in
my own local builds from git.

2018-11-12 Thread Didier Roche
I don't have the time to do a testround again, but I can give pointers
for whoever has time to have a look:

The patch is 
https://git.launchpad.net/~ubuntu-desktop/ubuntu/+source/gnome-shell/commit/?id=ddc4f511abd64d69c1150a41475d0a1ebac01dbb,
 in particular:
systemBackground = new Meta.Background({ meta_display: global.display });
[res, topColor] = Clutter.Color.from_string('#6D2169');
[res, bottomColor] = Clutter.Color.from_string('#370026');
systemBackground.set_gradient(GDesktopEnums.BackgroundShading.VERTICAL, 
topColor, bottomColor);

This is hardcoded in the Shell code (I made it conditional by session
type). This was made to match what is in the Yaru.css file:

#lockDialogGroup {
  background: none;
  background-color: none;
  background-gradient-direction: vertical;
  background-gradient-start: #6D2169;
  background-gradient-end: #370026; }

As I don't have bionic/cosmic eyes as yours, for me, for the short while
this screen appeared, ti seemed the same gradient, with the same
VERTICAL transition.

It does make this bug worse. The original bug was barely noticeable, but
with that fix it's really a bright and obvious glitch.

What we could do is release the SRU but just keep this bug open.

2018-11-12 Thread Sebastien Bacher
Daniel, ok you consider the fix here as problematic. Do we believe it's worth 
unvalidating the SRU over it though? We have enough difficulties landing 
gnome-shell SRUs fixing at the moment and the touch event one included in the 
same update is important to oem.
If the background change is not perfect but not worth than we had perhaps we 
can mark it verified, get that SRU in on the principle that it's not really 
making things worth and have another go later at fixing it more correctly?

Yes, I have now tested the proposed fix on two separate fresh
installations of cosmic. One HP and one Lenovo laptop. In both cases
they show a weird multi-stop gradient after the fix is installed. Looks
like the colour goes up-down-up-down instead of just down.

Are you sure it's differently? Look at the diff, it's supposively
exactly the same values than Yaru. Please check it and revert the status
as needed.

The proposed fix 3.30.1-2ubuntu1.18.10.1 certainly changes things, but
is equally broken as the original bug. Using the proposed fix a weird
gradient flashes up briefly that doesn't match the login screen
background and is more visually distracting than the original bug.

Hello Daniel, or anyone else affected,

Accepted gnome-shell into cosmic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/gnome-
shell/3.30.1-2ubuntu1.18.10.1 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 on 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-cosmic to verification-done-cosmic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-cosmic. In either case, without details of
your testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.
