The database from the session has been rebuild. The link is good to go.

I had a quick look at the pernsoco trace. The 0 alpha pixels are coming from:
:SurfacePipeFactory::CreateSurfacePipe () at /SurfacePipeFactory.h:555
mozilla::image::SurfacePipeFactory::MakePipe<> () at /SurfacePipeFactory.h:587
mozilla::image::BlendAnimationFilter<>::Configure<> () at /SurfaceFilters.h:682
::SurfaceFilter::ConfigureFilter () at /SurfacePipe.h:508::SurfaceFilter::ResetToFirstRow () at /SurfacePipe.h:114
::BlendAnimationFilter<>::DoResetToFirstRow () at /SurfaceFilters.h:714
::BlendAnimationFilter<>::WriteBaseFrameRow ()__memset_avx2_unaligned_erms at /memset-vec-unaligned-erms.S:259
Andrew is probably a better person to reason about what's supposed to be happening here.

It appears it is a corrupted GIF that doesn't write any pixels. The BlendAnimationFilter memset clears the initial memset to 0xFF we do because it is BGRX. Then the assert trips.

Is there a real-world impact for this bug which would make us want to consider uplifting this fix to Beta for 73 or can this ride 74 to release?

Bug 1516761 - Only use OS_RGBA for the first frame of animated GIFs.
Beta/Release Uplift Approval Request
- User impact if declined: May experience content process crash in Skia due to malformed GIFs.
- Is this code covered by automated tests?: Yes
- Has the fix been verified in Nightly?: Yes
- Needs manual test from QE?: No
- If yes, steps to reproduce:
- List of other uplifts needed: None
- Risk to taking this patch: Low
- Why is the change risky/not risky? (and alternatives if risky): It makes us use alpha surfaces more. Those support all the same situations as opaque surfaces, but more, with a minor performance cost. Given it is an animated GIF, most of the frames will be marked as containing alpha anyways, the first was just an exception.
- String changes made/needed: N/A
