Trying the Webrender.

Found this problem with dashed:

{ border-bottom: 1px dashed #006951; } - is not rendered correctly.

Look at:

Problem exists only with Webrender.
Can you attach a screenshot?
Nightly 59 x64 20171120100042 de_DE 5c48b5edfc4ca945a2eaa5896454f3f4efa9052a @ Debian Testing (KDE, Radeon RX480)
fresh profile: layers.acceleration.force-enabled, gfx.webrender.enabled, gfx.webrender.blob-images

The dashed line he mentioned seems fine for me, but another dashed line is just a solid white line.
This is not a regression. All earlier builds (2017-11-01, 2017-10-20, 2017-09-02) look like attachment 8930141 [details] for me. 20170701100236 (2017-07-01) has even both: A solid white line below a dashed line.

Actually it does not matter what video card is used. On my notebook with integrated Intel graphics I see the same line without dashes.

Eugene, can you confirm if it's fixed? Thanks.

WFM. There would be a small optical change compared to Gecko, but it's the most pretty from all, I think.
Verified in comment 11. This also fixed bug 1429614. Thank you, Ethan! :'(
