Back home, taking a look at this bug and showing the screenshots to a friend. And I just realized those screenshots look perfectly normal.
Probabaly because I took them with the screenshot feature integrated in Nightly.
I just feel like someone who would take a screenshot of their phone to show people what their broken screen looks like.

It will have to wait until monday to get "proper" screenshots of the bug. Sorry for not having checked the screenshots before...

Screenshot showing (really) the issue on a new tab page.

Bugzilla new bug page showing this bug (also scrollbars are black). But everything works, it's just black...

Dropdown menus, checkboxes, filepicker button (and its text)... A lot of elements are affected.
But they are functional, I submitted these screenshots with the bug.

I have found that when this occurs, I can make the problem go away with the "Trigger Device Reset" button in about:support.


Steps to reproduce behavior:
 > Freshly launch Firefox nightly with WebRender enabled (per WebRender newsletter 11 instructions: https://mozillagfx.wordpress.com/2018/01/03/webrender-newsletter-11/)

Steps to mitigate behavior:
 > Make sure a tab is open showing DOM elements replaced with black rectangles
 > Open a new tab, go to about:support
 > Under Graphics : Diagnostics : Device Reset, click "Trigger Device Reset"
 > Check other tabs to confirm that the problem has been mitigated.

1-2 "Trigger Device Reset" clicks may be needed to restore display back to normal.

I have also noticed that when the device resets, the shadows on tab titles becomes a lot clearer.

This attachment shows how to mitigate the effects of this bug.

When encountered, open about:support and trigger a Device Reset.

    "name": "Firefox",
    "osVersion": "Windows_NT 6.1",
    "version": "59.0a1",
    "buildID": "20180111100722",
    "userAgent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:59.0) Gecko/20100101 Firefox/59.0",
    "safeMode": false,
    "updateChannel": "nightly",

Do you still have WebRender after triggering device reset?  about:support graphics section would tell us that.

Comment 12

[Baudouin Feildel]

I have the same issue here. Triggering device reset solve the issue, but the compositor is back to Direct3D 11, no more WebRender.

This seems like dup of Bug 1433696.

The fix is actually working Bug 1434522. When D3D device does not support NV12 format, ANGLE does not handle eglCreateStreamProducerD3DTextureNV12ANGLE() and eglStreamPostD3DTextureNV12ANGLE() functions.

Comment 15

[Sotaro Ikeda [:sotaro]]

:flore, can you confirm if the problem is addressed with latest m-c?

Comment 16

[Sotaro Ikeda [:sotaro]]

Sorry, latest m-c means latest nightly.

Comment 17

[Flore Allemandou [:flore]]

I would say, this bug is fixed. No more black boxes.
As for the rest of the interface, it probably deserves a new bug (probably already filed) because all interface elements (buttons, icons...) disappeared.

Comment 18

[Baudouin Feildel]

Everything is fine for me, no black boxes and interface is ok.

[Sotaro Ikeda [:sotaro]]

Good! Thanks.
