1587084 - WebRender does not display anything if picture caching is disabled

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect, P2)

Description

[Nicolas Silva [:nical]]

This with the gfx.webrender.picture-caching pref turned off (on by default). The Window renders entirely transparent which renders the browser unusable.

The problem was fixed after I manually removed the pref from my the pref.js file of my profile.

We should do something ASAP, at least ignore the pref until a good solution to the problem is found and landed.

The framebuffer clear was accidentally removed due to a rebase
error. We need to clear the framebuffer (and z) here when the
non-picture caching path is active.

The previous patch fixed the bug in the non-picture caching code
path, so we can re-enable the preference now.
