Do we have a diff of the preferences that change between Nightly and Aurora?
Flags: needinfo?(mstange) → needinfo?(ryanvm)
Not that I know of. Maybe go through https://dxr.mozilla.org/mozilla-central/source/mobile/android/app/mobile.js and https://dxr.mozilla.org/mozilla-central/source/modules/libpref/init/all.js for instances of NIGHTLY_BUILD? Assuming it's not something controlled at the ifdef level, anyway.

I'll try to bisect it down in the meantime too.
Flags: needinfo?(ryanvm)
Using my ghetto hacked-together script [1] I get these differences. There might be more.

Thanks! layers.low-precision-buffer sounds like the most probably cause here.
Yeah, especially considering the patch I landed in bug 1151071. Thought that one doesn't touch the content type of the layer itself, only of the tiles that back it. And the reftest shouldn't need low resolution tiles... hmm, not sure what's going on here after all.
Oh, I thought you were going to bisect through the prefs, not through the changesets. Still useful though, thanks.
I'm also realizing that this a Beta-only failure, so RELEASE_BUILD is probably the more relevant ifdef here.
Diff with and without RELEASE_BUILD on trunk m-c:

Try bisection confirms that this started when bug 1263192 landed.
This is hitting the Aurora simulations now, so I think we're back to comment 3 being relevant again :\
Summary: opaque-fractional-displayport reftests are going to permafail on Android when Gecko 49 merges to Beta → opaque-fractional-displayport reftests are going to permafail on Android when Gecko 49 merges to Aurora
See https://bugzilla.mozilla.org/show_bug.cgi?id=1270241#c4 - snorp's "no bug" patch to revert the layers.low-precision-buffer change got backed out because of these same reftest failures. So that's probably the relevant pref.
That is extremely useful information, thank you.
I don't care who does what to them, but getting rid of the permaorange blocks opening mozilla-aurora.
Severity: major → blocker
as philor mentioned this is a blocking reopening mozilla-aurora so could you please take a look at this so that we are able to reopen the trees, thanks!
Flags: needinfo?(mstange)
Sorry for losing track of this. I thought snorp's changeset to disable the test had landed in time to merge to Aurora. Has it not? I can disable the test on Android after lunch.

The test is a new test and not particularly important on Android, because lowres tiles are not opaque anyway. But since I don't completely understand why it fails, I didn't want to disable it earlier. But that time has passed now, and I still haven't got a chance to find out what happens, so we should disable the test on Android.
Snorp will disable the test. He didn't do it yesterday because inbound was closed.
