1722728 - Display weirdness on MacOS Big Sur 11.5.1

Status: RESOLVED INVALID

(Core :: Layout, defect)

Description

[jeff]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Updated to 91.0b8
Loaded tt-rss from private site

Loaded 91.0b8 from the beta channel. Same problem

Loaded 90.0.2 Problem resolved, but not possible to restore data from Aurora to Main

Actual results:

Tree widget icons didn't load. Display seems similar to high-contrast safe mode. I also suspect some javascript didn't run.

Expected results:

All tree widgets (Dojo javascript library) should be displayed.
I also see issues with cors on Discourse. No cors-related messages displayed in the console log
I suspect MacOS as I noticed this when opening tt-rss after the just released Big Sur update. I don't see this behavior in Safari or Chrome.

Hi jeff,

Thanks for the report. Can you add a screenshot of the issue so I can try replicating on my end?

Does this issue happen with a new profile? Here is a link on how to create a new profile: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

Are you using add-ons? If so could you please list them? (you can try the issue while in Safe Mode. You can find helpful info here : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .)

Does this issue occur in the latest nightly version of firefox? Here is a link from where you can download it: https://www.mozilla.org/en-US/firefox/channel/desktop/

Best,
Clara

I've added a screenshot of the site under a fresh profile.

Are you using add-ons? If so could you please list them? (you can try the issue while in Safe Mode. You can find helpful info here : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .)
I'll try it in safe mode

I'm on Aurora channel, so I think the answer is "yes"

Best,
Clara

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

The Bugbug bot thinks this bug should belong to the 'Core::Layout' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Do you have "Increase contrast" in the macOS settings set? If you go to about:preferences, then Colors, then change "Override the colors specified by the page with your selections above" to "Never", does it behave as you expect?

Hi Emilio - Sorry, I've been working on moving to Debian from MacOS, and I did not see this message.
Yes, that fixes the issue.

I'm pretty sure this has been a setting for a while, and it just showed up with the recent beta release. /me shrugs.
Thanks for your help!

Yeah this is sorta expected, this is firefox's way of honoring that system setting on macOS. So I think this is working as intended but if many users get confused we might want to make it opt-in...
