Build ID: 20180112100121

Steps to reproduce:

Version: Nightly 59.0.a1 (2018-01-12) 64bit
OS: Pop_os! (Ubuntu 17.10)
GPU: NVidia 1060

Steps to reproduce:
    1: Open Firefox
    2: Go to a website like tweetdeck.twitter.com, or buzgilla.mozilla.org

Note 1: When creating a screenshot with Firefox Screenshots, in the picture the web page is ok.
Note 2: When clicking on the sandwich menu, it seems the page redraws because everything re-appear the right way then.


Actual results:

The background and some elements like text are rendered in black or in variations of black color, and some elements have bad positions


Expected results:

The page should be rendered properly

Andrew, do you get proper webrender just by setting gfx.webrender.all preference and none of the other ones?  E.g., no forcing acceleration, shared mem images or blobs?

[Andrew Osmond [:aosmond] (he/him)]

Yes, it is all as expected for me on Ubuntu.

They failed to create a GL context for WebRender, and then fellback to non-WR OpenGL (which apparently worked):

> "[GFX1-]: Failed GL context creation for WebRender: 0",
> "[GFX1-]: GLFeature::frag_color_float failed support probe, disabling. (RENDERER: GeForce GTX 1060/PCIe/SSE2)",
> "[GFX1-]: GLFeature::frag_color_float failed support probe, disabling. (RENDERER: GeForce GTX 1060/PCIe/SSE2)",
> "[GFX1-]: Compositors might be mixed (5,2)",

On 2018-01-09 I saw nearly the same failure log when I ran --find-fix for bug 1421747.

I can still reproduce (but with the new pref): Just a fresh profile + gfx.webrender.all and opening about:support:
> GLFeature::frag_color_float failed support probe, disabling. (RENDERER: AMD Radeon (TM) RX 480 Graphics (AMD POLARIS10 / DRM 3.19.0 / 4.14.0-2-amd64, LLVM 5.0.0))
But Bugzilla isn't black for me.

I have this issue with other websites too (in fact all I have seen) until I click on the Firefox menu.

[Jeff Muizelaar [:jrmuizel]]

Does this still happen?

[Maire Reavy [:mreavy]]

Hey Darkspirit -- Can you still repro this?  We're waiting to hear back from the reporter, but it'd be good to know if you still see any issue.  Thanks!

This might have been fixed by bug 1401455.
