1652823 - The fixed header on soundcloud.com does not dissapear when I switch to a tab containing another fixed header (azbukasantehniki.ru)

Status: NEW

(Core :: Graphics: WebRender, defect)

Description

[haypro.narek]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

1. Open tab https://azbukasantehniki.ru/catalog/kotly_otopleniya_dlya_chastnogo_doma/kotel_gazovyy_nastennyy/
   Scroll a bit down till the fixed header appears.
2. Create a new tab and log in and play music as usual on https://soundcloud.com/discover
3. Make sure you have a fixed dark header on soundcloud.
4. Now switch the tab to azbukasantehniki.ru

Actual results:

The dark header of soundcloud.com does not disappear after switching to azbukasantehniki.ru. I can see it over azbukasantehniki.ru. Again: I see the upper bar from soundcloud.com over the another site azbukasantehniki.ru.
See here: https://youtu.be/rLcRikocbl8

Expected results:

The upper bar should disappear.

Can you attach the contents of your about:support as a text file?

Attachment: issue reproed

I was able to reproduce the issue on my Mac with WR enabled after scrolling around a bit on both sites and playing music on Soundcloud. I have also been trying to repro with WR disabled and have not been able to make it happen yet.

GW - can you repro? Any suggestions?

[Glenn Watson [:gw]]

I haven't been able to reproduce locally so far (tested on a Mac and a Windows machine). Jessie, how easy is it to reproduce - was it happening regularly or just once?

Would you be able to set gfx.webrender.compositor to false, restart the browser (need to do an exit from dock on Mac), and see if you can reproduce then? (I suspect that will stop it occurring - not a good fix - but would help narrow down what part of the code may be causing it). Remember to change that pref back to normal after testing though!

[Jessie [:jbonisteel] pls NI]

I reproduced this pretty easily yesterday, but am not able to do so yet again today. Will keep trying.

haypro.narek, does this reproduce for you easily, every time you visit these two pages? Do you ever see it with other websites?

[Brunno Pleffken [:bpleffken]]

I've been able to reproduce this issue several times (Firefox Nightly 20200716094032 on MacOS Catalina w/ default [enabled] WebRender and OS compositor settings). When changing tabs some content of the previous tab is still being rendered.

Brunno - can you still reproduce this issue in Nightly? I suspect what you saw might be fixed and different from the original bug

This seemed to be fixed just a few days ago, but I could reproduce it now.
I just enabled an extension (using Cmd+Shift+A) and created a new tab using Cmd+T.

Comment 11

[Darkspirit]

We had two regressions that looked similar:
Bug 1653413 caused regressions with DirectComposition on Win10.
Bug 1640960 caused regressions on macOS.
Comment 0 might have been caused by Bug 1653413, and comment 2, comment 10 by bug 1640960.

Comment 12

[Darkspirit]

Sorry, I have to correct. Different bugs have been mixed:
comment 0 is Win10 WebRender on 79.0b4. Therefore it can't be bug 1653413 or bug 1640960.
comment 2 and comment 10 were caused by bug 1640960.

Comment 13

[BugBot [:suhaib / :marco/ :calixte]]

The component has been changed since the backlog priority was decided, so we're resetting it.
For more information, please visit auto_nag documentation.

Comment 14

[haypro.narek]

I can reproduce this in 80.0b8. Here is another demonstration of the bug: https://youtu.be/LCRGRy5n4kk

Unfortunately I can not recognize the exactly conditions to reproduce it.

Comment 15

[Kris Taeleman (:ktaeleman)]

@ktaeleman: try repro

Comment 16

[Kris Taeleman (:ktaeleman)]

Still easily reproduces on latest nightly with repro steps of reporter.
@Glenn: gfx.webrender.compositor false does not show the issue, so it must be related to this.

Let me know if you want me to generate some logging or so!

Comment 17

[Markus Stange [:mstange]]

I can reproduce this bug on macOS.

Comment 18

[Glenn Watson [:gw]]

I haven't been able to reproduce locally yet, but will try again today / tomorrow. Markus is going to try and look at it this week as he is able to reproduce locally.

Comment 19

[Markus Stange [:mstange]]

I can no longer reproduce this :(

Comment 20

[Kris Taeleman (:ktaeleman)]

@Kris try repro again

Comment 21

[BugBot [:suhaib / :marco/ :calixte]]

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.
