1454610 - DMG quantum background image not properly sized

Status: VERIFIED FIXED

(Firefox :: Theme, defect, P2)

Description

[Axel Hecht [:Pike]]

Attachment: Screen Shot 2018-04-17 at 12.35.50.png

While trying the DMG from http://archive.mozilla.org/pub/firefox/candidates/60.0b8-candidates/build1/mac/de/, I found that the background graphic gets the scaling wrong.

Attaching a screenshot.

I have a non-retina secondary monitor, but the dialog showed on my retina display, maybe that's part of it.

Comment 1

[Gyula Palko[:gpalko]]

Reproducible on Mac OS, all Quantum builds.

Comment 2

[Molly Howell (she/her) (mostly inactive)]

Yeah, this reproduces on my non-retina MacBook too (running 10.13.4). Between this and bug 1439072 I'm definitely starting to think we're coming up against Finder bugs.

Comment 3

[Molly Howell (she/her) (mostly inactive)]

:spohl, do you have any ideas about this, or know someone better to ask? Because I've got nothing.

Comment 4

[Stephen A Pohl [:spohl]]

I don't know off-hand. I would set a need-info on whoever added this background graphic to see if this is a known issue and to get this addressed.

Comment 5

[Molly Howell (she/her) (mostly inactive)]

Looking into that is taking me through a whole list of people who are no longer active. :( Well, and also :glandium, but this doesn't really seem like his problem. I wouldn't mind owning this thing myself, I just don't know how to even start investigating these bugs; my Mac expertise is limited anyway, and this is a particularly esoteric corner even within that realm. But I'll see if there's anything I can do.

Also, I've just discovered in the process of looking into this bug that the current dev edition release just doesn't show the background art at all, apparently because the volume name isn't what the prebaked .DS_Store file expects. So that's cool. I'll file that separately, I guess.

Comment 6

[Stephen A Pohl [:spohl]]

Feel free to kick this over to widget:cocoa and mark it as P2 if you can't find the time to look into it. I will prioritize alongside other platform work.

Comment 7

[Molly Howell (she/her) (mostly inactive)]

Okay, you've got bug 1455768. Congratulations. ;)

I'll move this and bug 1439072 over there also.

Comment 9

[Nick Thomas [:nthomas] (UTC+12)]

This affects Firefox from 60.0, including 60.0esr and the 61.0 betas. Not present in 59.0.

Comment 10

[Justin Dolske [:Dolske]]

This has broken before, the process to make this all work is a bit delicate/complicated...

See bug 1435359 comment 2 on the steps that are normally needed to do this.

I don't see any changes to the DSStore file since, although bug 1234008 did touch the background.png used... Stephen, was there anything special about the PNG used that might have been affected by the image optimizer?

I wonder if we need to figure out a way to automatically test this... Screenshot the Finder window, and compare with a reference image? Add it to the QA manual verification for Release?

Comment 11

[Justin Dolske [:Dolske]]

Tim: Anything you see in the old-vs-new background.png that changed?

Comment 12

[Tim Guan-tin Chien [:timdream] (please needinfo)]

Comment 1 and comment 9 contracts to one another.

Anyway, I've tried to see https://ftp.mozilla.org/pub/firefox/releases/59.0.3/mac/en-US/Firefox%2059.0.3.dmg and it shows up correctly. Nightly seems unaffected.

Will dig deeper... keeping needinfo.

> Nightly seems unaffected.

Nightly is not affected because the image is not hi-res anyway.

From tools, I can see the original background.png comes with DPI set to 144 pixels/inch.
https://hg.mozilla.org/mozilla-central/raw-file/69c3cb2e731c/browser/branding/official/background.png

Playing around with Preview.app and exiftools I can see the following command will allow the new file to be displayed in the same dimensions as the original file in Preview.app.

exiftool -XResolution=144 -YResolution=144 -PixelsPerUnitX=5669 -PixelsPerUnitY=5669 background.png

I'll push a try build with this change.

[Tim Guan-tin Chien [:timdream] (please needinfo)]

Try result confirms this bug can be fixed by comment 13.

I am not entirely sure how to prevent this footgun in the future. Taking a screenshot of the Finder window is perhaps an overkill?

How about implementing a small PNG parser in mochitest to read out the metadata tags? Would that be sufficient? Do we have that in the tree already?

Hum, that won't work -- we don't put these files in the jarfiles.

Comment 18

[Tim Guan-tin Chien [:timdream] (please needinfo)]

This affects install experiences, perhaps we should uplift.

Comment 19

[Ryan VanderMeulen [:RyanVM]]

Too late for ESR 60.1 and Fx61 at this point (we're already building RCs), but this seems like a good dot release ride-along candidate should the opportunity arise.

Reading the rest of the comments, it seems like the issue is some processing of PNGs stripping the meta information from the PNG?

Yeah, I'm not really sure we have test infra set up for that. You'd also need the test to be able to differentiate between Nightly/DevEd/Release, and screenshots can be annoying if slight differences exist (e.g. maybe scaling is slightly different on some OS versions).

Maybe easiest thing to do here is have QA add this to their list of periodic release checks?

Do we want a hidpi image for the Nightly DMG? If so, new bug w/ desired image.

Yes, let me know if there is an asset ready and I can compress and land it.

[Feature/Bug causing the regression]: Bug 1234008
[User impact if declined]: Mac installer will come with an incorrect background
[Is this code covered by automated tests?]: No.
[Has the fix been verified in Nightly?]: Cannot be verified since this only affect official branding. Verified on Try in comment 15.
[Needs manual test from QE? If yes, steps to reproduce]: Manually inspect the Mac installer on Beta and official build
[List of other uplifts needed for the feature/fix]: No.
[Is the change risky?]: No
[Why is the change risky/not risky?]: Just an asset update.
[String changes made/needed]: None.

Can this also ride-along a dot-release in 61? Do we want to take this in esr60 too?

Fix for recent regression. Let's take this for beta 4 and verify it in beta.

Managed to reproduce  with the link provided in comment 0. 
Fixed on latest nightly (63.0a1 - 2018-06-29).

Still reproducible on 62.0b4, Timothy can you take a look at this please?

Comment 34

[Tim Guan-tin Chien [:timdream] (please needinfo)]

I cannot reproduce this on 62.0b4, downloaded from this URL

https://download-installer.cdn.mozilla.net/pub/firefox/releases/62.0b4/mac/en-US/Firefox%2062.0b4.dmg

(redirected from https://download.mozilla.org/?product=firefox-beta-latest&os=osx )

I am on macOS 10.12.6.

Perhaps this can only reproduce on a different macOS version?

Comment 35

[Cristian Fogel [:cfogel]]

Rechecked on macOS: 10.9.5, 10.11.6, 10.13.4.

The fix is working after all with both the provided link and a download from http://archive.mozilla.org/pub/firefox/releases/62.0b4/mac/en-US/

During the re-testing I've noticed a scenario that was causing the issue to re-appear:
- opening the installer from the affected build;
- close it and open the 62.0b4 build.
The layout is still the broken one.

How should we proceed next; mark this as fixed and open up a follow-up bug or [...]?

Taking this as a ride-along for Fx 61.0.1. Please also request ESR60 approval on it when you get a chance.

Please file a new bug. Mounting different builds is unlikely something ordinary users do every day. Thanks.

Given that you have the flag that already I assume I don't need to do anything more here?
