In 56.0b4 (64-bit) with Stylo enabled, I see -webkit-linear-gradient taking precedence over legacy -moz-linear-gradient. Simultaneously it seems as if the starting position, which is specified as "bottom" (not prefixed with "to"), is being treated as if it were "to bottom". In the attached screen capture from the developer tools, when processed by Stylo, the -moz-linear-gradient directive is disabled. When the same set of directives is processed without Stylo, the -moz-linear-gradient directive takes precedence and renders as expected: with the gradient starting from the bottom. For whatever it's worth, the site I am seeing this on is an old intranet app, and I can easily update the styles to align better with current best practices for specifying gradients. Nevertheless, I figured I'd mention this small change in behavior.

(I'm just a Nightly user.) Hi, I can't reproduce your testcase in Nightly 57 x64 20170822142709 @ Debian Testing, so I think this has been fixed by bug 1391432 (or I was incompetent). If I understood it correctly, the Stylo Experiment in Firefox Beta gets crash fixes, but not other bug fixes to (only) help with stability testing (bug 1385831 comment 13). To get a better impression of Stylo you could test Nightly: https://nighty.mozilla.org I leave this open so someone else could mark this as duplicate of bug 1391432 if it's true.

Sorry, I mean https://nightly.mozilla.org

Brian, can you re-test on Nightly?

Jan Andre is correct, this appears to be fixed in the current Nightly build. Sorry for the false alarm, folks. And thanks for Stylo and all the other cool stuff in the pipeline!
