With WebRender enabled, it seems that anything completely opaque (no transparency including rounded borders, such as most backgrounds) does not get drawn, letting the window's color pass through.

Firefox Nightly, Arch Linux.

Vendor ID:      NVIDIA Corporation
Device ID:      GeForce GTX 980M/PCIe/SSE2
Driver Version: 4.6.0 NVIDIA 390.25

Driver version 387.34 was also affected.

fresh profile: gfx.webrender.all, gfx.webrender.debug.alpha-primitives
WFM.

This reminds me of bug 1432261 (Native GL on Win10).

Oh, this might be a duplicate of bug 1401455 (compare with attachment 8943091 [details]).

Could you open that page again and about:support afterwards?
Do you see a failure log at the bottom of the graphics section? What does it say?

Nightly 60 x64 20180131100706 en_US, GNOME X11.

I had a fresh profile, gfx.webrender.all, gfx.webrender.debug.alpha-primitives.

I also selected the "A Web Browser Renaissance" theme for the obvious brown color. Note that the chrome is also affected and the toolbars are missing the background image.

Tried again and no failure log. I agree this is probably a duplicate.
