Bug 1800367 - For Linux, don't add an FTUserFontData when instantiating an installed variation font. r=lsalzman
48 bytes, text/x-phabricator-request
Details | Review

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0

Steps to reproduce:

  1. Install a variable font in the operating system. I have tried with the variable version of Inter from https://github.com/rsms/inter/releases/tag/v4.0-beta7 and Recursive from https://github.com/arrowtype/recursive/releases/tag/v1.085
  2. Open up Firefox with a fresh profile, and visit the following URL: data:text/html,regular<b>bold
  3. The text "regular" is non-bold, the text "bold" is displayed in bold
  4. In about:preferences → General → Fonts, change the default font to "Inter" (or whatever variable font you installed)
  5. Switch back to the data: URL above

Actual results:

Both "regular" and "bold" are displayed in the regular weight

Expected results:

The text "bold" should still be displayed in bold, as with non-variable fonts.

This worked as expected a couple of days ago, Wednesday the 9th at the earliest.

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

Thanks for the report. I'm guessing this is almost certainly a regression from the patch in bug 1798036. I'll look into it.

Regressed by: 1798036

This in effect reverts bug 1798036 for desktop Linux, as the fix there
was really only needed for Android, and turns out to conflict with how
the FC-based backend handles variations.

Tested locally; currently no reftest because we cannot assume presence
of an installed variable font.
