See https://bugzilla.mozilla.org/show_bug.cgi?id=920921#c55  Homescreen wipe should not cause a buffer rotation to happen.  Other bugs are handling the efficiency of rotation/unrotate, but this bug is to remove the reason for those optimizations.

Milan - Can you clarify why this is a homescreen bug and not a gfx bug?
Flags: needinfo?(milan)
https://bugzilla.mozilla.org/show_bug.cgi?id=920921#c55 has a proposal as to a change to homescreen should be: "We should never ever hit buffer rotation. We should just pre-render whole planes. We need a separate bug for this and have to see what triggers the buffer rotation."

Milan, can you triage this for 1.3? Is this blocking?
Flags: needinfo?(milan)
Should be blocking, but according to https://bugzilla.mozilla.org/show_bug.cgi?id=920921#c75, we have patches that fix this.  Assigning to Peter as he is assigned to bug 920921.

Looks like this should be linked to the flatfish parent bug.

Moving from 1.3+ to 1.4+ since Flatfish will use 1.4.

FxOS Perf P1 as this has a direct negative impact on Frame Uniformity.

Milan, do these findings also apply to our non-flatfish devices?

Sure, but it doesn't show because of the smaller resolution and faster gralloc implementation.  I think this is still actionable, on the Gaia (layout?) side, even though the bug 915673 will get rid of buffer rotation in the first place.

That was meant to be bug 963073, rather than 915673.
This doesn't fall under the QC blocking feature list & DSDS feature list. Renoming.
blocking-b2g: 1.4+ → 1.4?
Moving to backlog - flatfish doesn't hit the QC feature list & DSDS feature list.
blocking-b2g: 1.4? → backlog
As long as we don't back out tiling this now should be fixed WFM.
