1505664 - Increasing shared texture cache to 64 layers breaks rendering on mac intel OpenGL driver

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect)

Description

[Bobby Holley (:bholley)]

Gankro reported this in the latest nightly: https://usercontent.irccloud-cdn.com/file/6RB5F0Mw/Screen%20Shot%202018-11-07%20at%209.40.34%20PM.png

This appears to be mac only, and only when using the integrated card (I need to unplug my external display to reproduce it).

I've confirmed it's caused by bug 1495977, specifically the increase in texture layers from 4 to 64. Rendering is fine up to 32 layers, then breaks at 33 layers.

As a stopgap, I'm going to reduce from 64 to 32 layers, and have the sheriffs respin Nightly. Will look more tomorrow.
