Works in Nightly 46.

Tracking as it is an obvious and visual regression.

I found that disabling e10s makes this bug much easier to reproduce. It also reproduces on trunk that way.

Regression range: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=ddd566eb39b7a39d0ff630343f179fedc8fcafd5&tochange=7e18014be68d9e13760b2814862745911caf49a5

Regression from bug 1168263. Probably a dupe of one of the other blockers hanging off it, but we can figure that out if/when one of them actually gets fixed.

Also, I was only able to reproduce this on Linux. Windows 10 WFM regardless of whether e10s is enabled or disabled on both trunk and aurora.

Comment 2 suggests that this is already fixed in 46, is that what you're seeing?

I've just landed all the outstanding fixes I have, so hopefully this just needs an uplift to aurora.

On Linux I was able to reproduce on trunk as well with e10s disabled. I can also confirm that current m-c tip still reproduces the issue, so I suspect that this isn't going to be fixed on Aurora by uplifting whatever patches have already landed.

I can still reproduce the problem on Windows Nightly46.0a1 if I disabled both HWA and e10s.

Ok, I can reproduce this in a local build with HWA disabled.

Verified on trunk. Ready for an uplift request? Also, I'm wondering if we can land a test for this. We've had a lot of preserve-3d related regressions lately, which is concerning from a test coverage standpoint.

Tracking for 45+ this is a regression.

	Matt Woodrow (:mattwoodrow) Assignee
	Comment 14 • 9 years ago

We're probably going to be backing the regressing bug out of Aurora as part of the preserve-3d backouts, so I'll wait on requesting uplift.

	Ryan VanderMeulen [:RyanVM]
	Comment 15 • 9 years ago

The change that caused this regression was backed out from Firefox 45. A current Developer Edition build should now work correctly, or you can wait until 45 goes to Beta some time next week.

Confirmed from my side.

Thanks !
