Comment 1

[:Gijs (he/him)]

This looks like bug 1386643 to me. Please check if it's fixed on today's nightly.

Comment 2

[ovidiu boca[:Ovidiu]]

I tested with Nightly 57 (2017-08-11) and if I hover the mouse over tabs the text from URL bar, search bar and tabs titles is changed.

Comment 3

[:Gijs (he/him)]

I'll add the photon tracking stuff back to avoid this getting lost, but this looks like a graphics issue to me. I can't reproduce. Markus, do you have any ideas?

Ovidiu, does this reproduce on all osx machines you have access to? Which version of OSX was the test recorded on?

Comment 4

[ovidiu boca[:Ovidiu]]

The recorder is made on Mac OS X 10.10 but I just retested on Mac OS X 10.12 and I can reproduce it.

Comment 6

[Markus Stange [:mstange]]

This is separate from the selected tab issue. It deserves its own bug.

Comment 7

[Markus Stange [:mstange]]

The patch in bug 1387296 fixes this.

Comment 8

[Marcia Knous [:marcia]]

Tracking this visual issue for 57.

Comment 13

[atlanto]

I have exact same issue of bug 1389476 on Windows10. I can see it on LinuxMint 18.2 also. (two Intel HD Graphics machines)

STR:
1. Open multiple tabs
2. Move mouse on inactive tab

AR:
Font of tab title, urlbar, search text becomes a bit different shape(rendering) and back to normal quickly.

ER:
No such blur.

mozregression tells Pushlog:

If following style is applied with userChrome.css, this issue doesn't occur.

.tab-line:not([selected=true]) {
  transition: none !important;
}

BTW, this doesn't occur when gfx.webrender.enabled;true, it's OT though...

May I ask for a status update? It's a super annoying bug in one of the most important parts of the browser UI (the tabs!) and I can't see any progress since two weeks.

ni? :mstange because another week has passed, this ticket already has five duplicates and there are only three weeks left until Firefox 57 reaches Beta.

Confirmed with the latest nightly 57.0a1 (2017-09-05) (64-bit) on macOS Sierra 10.12.6 (latest stable).

Comment 20

[Markus Stange [:mstange]]

I'm going to put patches for this bug up tomorrow. Sorry for the long delay; I was on PTO since Friday, and this bug has a number of interacting pieces (and needs patches for different bugs) that I need some time to untangle.

Comment 24

[Markus Stange [:mstange]]

I just attached patches to bug 1387594 which fix this.

Comment 25

[Panos Astithas (he/him) [:past] (please ni?)]

I can confirm that this is now fixed after bug 1387594.

Comment 26

[ovidiu boca[:Ovidiu]]

Tested on Mac Os X 10.12 and Mac OS X 10.10 with FF Nightly 57.0a1(2017-09-18) and I can confirm the fix.

Comment 27

[Sören Hentzschel]

Attachment: favicon

There is still a strange effect on the favicon, please see the attached video. Is this another bug?

Comment 28

[Sören Hentzschel]

(please have a look at the most left favicon in the attached video, the purple envelope)

Comment 29

[Johann Hofmann [:johannh]]

Markus, could you take a look at comment 27? Thank you!

Comment 30

[ovidiu boca[:Ovidiu]]

Thanks for the video, unfortunately, I can't reproduce this behavior. Did you try with a new profile, what Mac version do you use? Markus, can you please take a look at Sören attachment from comment 27?

Comment 31

[Sören Hentzschel]

Attachment: favicons

I attached a new video which shows the issue better (it's not only one favicon affected).

It's on OS X 10.11.4. I can try on a new profile later today.

Comment 32

[Dirkjan Ochtman (:djc)]

I don't think I can see the favicon effect Sören mentioned, but I do see some similar effect on the widgets at the right side of the tab bar (> for scrolling tab bar, +, and downward arrow for container access). There also seems to be an effect on the dark icon of my right-most pinned tab and maybe the drop shadow on the left-most non-pinned tab? See attached movie.

Comment 34

[ovidiu boca[:Ovidiu]]

I can reproduce what Dirkjan mentioned in comment 33. I will reopen this issue.

Comment 35

[:Felipe Gomes (needinfo for replies!)]

Attachment: Yet another video

Sorry about piling up here, I just wanted to post another recording of this where I think it's easy to see the bug.

This is on the latest Nightly, with bug 1386643 fixed.

Comment 36

[:Atoll]

I am no longer able to reproduce the issue I filed as bug 1390639 (which was then duped to this seemingly-related bug) as of latest Nightly on an OS X retina computer.

Comment 37

[Joe Hildebrand [:jhildebrand] (UTC-6)]

Attachment: Font rendering with theme containing tab bar bitmap

Please also try this with a theme that uses a bitmap or something else interesting in the tab bar.  Tab bar text uglier than normal.

Comment 38

[Markus Stange [:mstange]]

I can reproduce the flashing favicons issue and filed bug 1401037 for it.

I have not been able reproduce bad quality text rendering with lightweight themes. Joe, could you file a new bug with a link to the theme you're using?

Comment 39

[Brindusa Tot, Desktop QA]

Verified as fixed on Mac OS X 10.12, with latest Nightly 58.0a1 and Beta 57.0b3.
