(20171123100420) Probably the same issue. Usually it only happens after some time. Theme: https://twitter.com/FirefoxNightly/status/933717466513072128
@Jan, I tried out that theme and thought it looked great except for the text; didn't even think about trying it on a non WR profile. Glad to know it's a bug.
This seems very visible to first-time WebRender testers -- shouldn't that make it [wr-mvp] (and > P3)?
This discoloration isn't always white, if engine thinks letter color is white enough, it will create black discoloration instead. (ex: https://addons.mozilla.org/en-US/firefox/addon/firefox-quantum-nightly/ )

I'm not able to reproduce this bug on OS X either using rev cdf4bb1c6af6e53643d2beb0f10a2ce29207ff5e ("first bad revision") or the current nightly. Might not affect OS X, or maybe it's intermittent, or maybe I'm just not seeing it. In the screenshot in comment 0 I can't see anything wrong; the screenshot in comment 2 shows some discoloration which is what I'm looking for and not finding when I try to repro.
I can still reproduce this. You need to use a light weight theme.
Ah, I see it in Nightly using either the "A Web Browser Renaissance" theme or the recommended "Pastel Gradient" theme. Doesn't show up with other themes as far as I can tell. I'll try to bisect into bug 1417062.
WR regression range is: * 54e79688 Auto merge of #2031 - glennw:pic28, r=kvark * fadae648 Address review comments and fix Gecko test failures. * 0633bb37 Hide StackingContext * 6ca43c34 Introduce PicturePrimitive::Image. I filed servo/webrender#2176 for it.

This is working in nightly, and after running mozregression + the Quantum Nightly theme, I found it was fixed by bug 1424673.

@Andrew, does that mean that the servo/webrender#2176 ticket should be closed as well? I can't do this, but figured I would ask.
