943112 - Settings has an (invisible?) opacity transition causing recomposites

Status: RESOLVED WORKSFORME

(Firefox OS Graveyard :: Gaia::Settings, defect)

Description

[Benoit Girard (:BenWa)]

I'm seeing APZC requesting 60 FPS when nothing is changing.

STR:
1) Turn on APZC for Settings
2) Scroll

When the scroll winds down we keep requesting 60 FPS when nothing is changing

I don't know that this is actually blocking bug 909877, but lets hang it off it for now.  Just no automatic 1.3+ for now.

I plan on fixing it now because it's making the control flow very messy.

Comment 3

We can't repaint with 60fps when idle, that would drain battery in no time. BenWa is right, this needs a fix now.

I don't mind if it gets fixed right now, but my understanding was that we keep requesting 60fps "for a while" not "forever" after scroll.  As in, a fraction of a second.  That's not the case?  Is this a regression?

That's correct. It will last maybe 500-100ms

And this isn't tied to APZC at all. I can reproduce it without it. It seems to be a bug with the settings app.

Comment 7

[Benoit Girard (:BenWa)]

Removing 1.3+ since I originally requested and I don't think given this new information we would prioritize this bug.

Can you help check the new status around settings?

Comment 9

This bug is probably obsolete. I'll refile if I see it again.
