750334 - rotating image appears too big during transition, then snaps to correct size

Status: VERIFIED FIXED

(Core :: Layout, defect)

Description

[Brad Lassey [:blassey] (use needinfo?)]

Attachment: screenshot of layed out too big

The site has a section at the top that rotates between 3 photos with a fade transition. During that transition, the images are layed out much too big. Once the transition is complete, they snap to the correct size.

So this is Fennec, not Mac desktop?

Comment 2

[Timothy Nikkel (:tnikkel)]

It seems so.

It is some problem with how we configure image layers when we optimize thebes layers into image layers. All it takes is an image that has its opacity animated to show the problem.

Maybe related to bug 741173? Though perhaps not, going on Joe's latest comment on that bug.

Ali, can you dupe this if it is a dupe?

The patch for Bug 728026 fixes Bug 741173 but doesn't fix this bug, so this seems to be a different issue.

To help debug this, I've made a minimal testcase at http://people.mozilla.org/~ajuma/opacity

As noted by tn in Comment 2, all that's needed is an image that has its opacity animated.

Yup, sorry. This is Fennec.

Indeed; turning off the thebes layer to image layer optimization prevents the problem.

I think this should fix the problem, can someone try it please :)

Is there a similar code path that might apply to frames of a video (bug 754434)? I can reproduce that bug even with the patch from this build.

Clearing the approval nom - this landed on aurora before migration, and should be uplifted to beta automatically
