+++ This bug was initially created as a clone of Bug #1409736 +++

I'm filing this as a placeholder bug for the next webrender update. I may be running a cron script [1] that does try pushes with webrender update attempts, so that we can track build/test breakages introduced by webrender on a rolling basis. This bug will hold the try push links as well as dependencies filed for those breakages, so that we have a better idea going into the update of what needs fixing. I might abort the cron job because once things get too far out of sync it's hard to fully automate fixing all the breakages.

When we are ready to actually land the update, we can rename this bug and use it for the update, and then file a new bug for the next "future update".

Green except for a slight increase in fuzziness for css-break/box-decoration-break-with-inset-box-shadow-1.html in R4. Regression range is

*   205cd083 Auto merge of #1910 - mstange:multiply-clip, r=glennw
|\
| * c42466c0 Always multiply alpha with the clip's alpha.
* 38f1d656 Auto merge of #1911 - mstange:bright-text-macos, r=glennw
* 8f3d9d7b Draw white on black if the font is bright, because bright text uses a different amount of font dilation.

So it's probably from servo/webrender#1910. (Related to this reftest: bug 1411074)

Slight increase in fuzziness for transform-3d/backface-visibility-2.html in R8.

Regression range:

*   3b1cf1e6 Auto merge of #1915 - mstange:fix-intel-clipping, r=glennw
|\
| * 854f8738 Use a different workaround that fixes both #1809 and #1738.
* bf1869de Auto merge of #1914 - mstange:premultiplied-rectangle, r=glennw
* 3da0b935 Use premultiplied blending for rectangle primitives.

Probably from servo/webrender#1918.

Green with a side of decreased fuzziness in css-break/box-decoration-break-with-inset-box-shadow-1.html in R4. Regression range is

* 1cb8e7f0 Auto merge of #1918 - glennw:bs-spread, r=kvark
* 782ca07d Fix inset box shadows with spread radius > border radius.

I tweaked the fuzz numbers to compensate.

Green
Right now builds are broken as of servo/webrender#1923. Gankro provided a gecko patch in that issue but it requires bug 1401653 to be in first, and that just got backed out of autoland. So we're on hold until that gets sorted out.

Much orange, looks like a crash in texture cache locking code. Regression range:

*   038a223b Auto merge of #1945 - lsalzman:color-bitmap-blend, r=glennw
|\
| * 9fb8ab8f remember GlyphFormat in glyph cache and pass to text run shader
*   c47d106c Auto merge of #1920 - mephisto41:improve-blur, r=glennw
|\
| * e1f0c80e Tweak blur filter.
* 844779d1 Auto merge of #1942 - kvark:flatten, r=glennw
* 72692761 Move flattening logic into FlattenContext
* 18b12e50 Synchonized font instance map

Nothing here looks super relevant so it might be a regression on the gecko side. I'll do some more try pushes to narrow it down.
I did the cross-build try pushes:

new WR with older autoland cset [1] - busted
old WR with newer m-c cset [2] - green

So this is definitely a breakage from a change in upstream WR. Bisecting the range from the last comment, but #1942 looks like the most likely culprit.

[1] https://treeherder.mozilla.org/#/jobs?repo=try&revision=346514879173d2bebc49ba846b9819c2dfa93b86
[2] https://treeherder.mozilla.org/#/jobs?repo=try&revision=705b6c62699a7ded031e0d2cc1e8b66c2b525d1d
Bisection push with WR @ 844779d1 confirms bustage: https://treeherder.mozilla.org/#/jobs?repo=try&revision=f4773a25f60ecf0e6cc22a615998a621f0e00586

So #1942 is definitely where it's coming from. :kvark is looking into it.
The fix is in servo/webrender#1948. Try push with that applied is at https://treeherder.mozilla.org/#/jobs?repo=try&revision=08b5790d2d7842580be509e4a516611a1f3bdccf - there are a bunch of reftest changes from #1920. I'll update the reftest results for those.
^ Linux is green (The R7 failure is because I fat-fingered one of the reftest adjustments). But Windows is red, getting another shader compilation failure:

thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: Link("debug_font", "Precisions for uniform \'uMode\' differ between vertex and fragment shaders\n")', src\libcore\result.rs:906:4

Looking back the try pushes the regression range for this is:

*   038a223b Auto merge of #1945 - lsalzman:color-bitmap-blend, r=glennw
|\
| * 9fb8ab8f remember GlyphFormat in glyph cache and pass to text run shader
*   c47d106c Auto merge of #1920 - mephisto41:improve-blur, r=glennw
|\
| * e1f0c80e Tweak blur filter.
* 844779d1 Auto merge of #1942 - kvark:flatten, r=glennw
* 72692761 Move flattening logic into FlattenContext
* 18b12e50 Synchonized font instance map

Based on the diffs I think this is coming from 9fb8ab8f, aka servo/webrender#1945.
