Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:99.0) Gecko/20100101 Firefox/99.0

Steps to reproduce:

  1. Open the Firefox home page and click on the address bar. The text in the address bar dropdown has grayscale anti-aliasing.
  2. Open a new window, go to the about:config page, don't change anything in the settings and click on the address bar. Now the same text in the address bar has sub-pixel anti-aliasing.

Actual results:

Thus, it turns out that the type of anti-aliasing changes arbitrarily depending on which page is open. And there is no way to turn it off or affect it in any way. The switching mechanism is automatic. Also, the anti-aliasing type itself changes when you open the developer menu.

Expected results:

I think that the type of anti-aliasing should not be changed implicitly for the user in a way depending on any factors that are not described anywhere. Perhaps a good solution would be a setting in the config, which unambiguously determines what type of anti-aliasing will be used. Or, for example, the choice between options:
auto | always grayscale | always subpixel.

I think "Graphics: Text" is more suitable
Additional:

  1. Pref gfx.webrender.quality.force-subpixel-aa-where-possible = true dont fix this, and the browser keep changing the anti-aliasing type in the bookmarks bar. Does this pref work at all?
  2. This cannot be fixed with a custom style shield as the antialiasing type specified in the css is ignored.

The severity field is not set for this bug.
:adw, could you have a look please?

Thanks for the answer. Maybe it's worth disabling processing when pref gfx.webrender.quality.force-subpixel-aa-where-possss is set to true ?
