1689510 - Text being shown in all black on OSX

Status: VERIFIED FIXED

(Core :: Graphics: WebRender, defect)

Description

[Andrew McCreight [:mccr8]]

All text is being shown in black in OSX in the latest Nightly. Turning WebRender off does not seem to help. I don't see this on Windows.

For instance, on this page, in the box with "popular color tags", the text is supposed to be shown in many different colors, but it is all black: https://www.colorcombos.com/font-color-tester.html

Needless to say, this makes dark mode sites almost impossible to use.

I'm not sure if this is only fonts or not. The big icons on the front page of bugzilla are being shown in black instead of gray.

It sounds like Mossop is seeing something similar.

Those "icons" are actually characters from the material ui font.

Mozregression says it is bug 1689316.

I'm not sure how that squares with it not going away if I turn off WebRender (I also tried turning off Fission in case that might help).

Did you turn it off using gfx.webrender.force-disabled=true?

Comment 7

[Andrew McCreight [:mccr8]]

No, I set gfx.webrender.all to false. I don't see the pref gfx.webrender.force-disabled, but I do see gfx.webrender.compositor.force-enabled. about:support does say I have WebRender on, so I guess I was failing to disable it.

Comment 8

[Andrew McCreight [:mccr8]]

Huh, ok, the force-disabled did show up when I searched for it. Setting that to true makes things work again, as expected.
