Status: RESOLVED DUPLICATE of bug 1459102

(Core :: Graphics: WebRender, defect)

Description

[aventura.viper]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0
Build ID: 20180504100129

Steps to reproduce:

Using latest Nightly Builds (from second build of 03/05 (Thursday 3rd May))on Windows 7 64bit with "gfx.webrender.all" set to true.


Actual results:

Firefox loads as blank white window and is unusable. Starting in safe mode and reverting webrender to false allows Firefox to start properly again.

Kats, should we reopen bug 1459102 and dupe this bug to the mac bug?

Aventura, can you try the build at https://queue.taskcluster.net/v1/task/S1g2Uj_NQO-1nmv0JVEwPA/runs/0/artifacts/public/build/target.zip to see if it has the problem as well? If not, then we can just dupe this to bug 1459102 since the backout that fixed that fixes this as well. If it's not the same problem we'll need to investigate more.

That has reverted it to the previous behaviour, so I guess that means this is a duplicate of bug 1459102. Thanks for your help!
