1602981 - All text broken in Nightly 2019-12-10 after updating

Status: RESOLVED DUPLICATE of bug 1603026

(Core :: Graphics: WebRender, defect)

Description

[:Atoll]

Attachment: About dialog

I updated to today's Nightly to test something unrelated, and uncovered a particularly interesting problem on macOS 10.15.1 and Nightly 2019-12-10. I believe I have webrender.gfx.all force-enabled for testing purposes, and this resembles past webrender issues. Is this known?

EDIT: Confirmed that disabling gfx.webrender.all repairs the browser for me.

Attachment: 60 seconds later, more of the developer console is affected, even though I didn't type anything.

Triaging over to WebRender (hope I set the fields right).

Most likely a dupe of bug 1603018.
