814392 - "WARNING: should already have refreshed style rule"

Status: NEW

(Core :: CSS Parsing and Computation, defect)

Description

This looks very similar to bug 650469

With B2G on the PandaBoard, the FTU app first displays the Firefox logo, but then blends into a static white screen and stops making progress. On the console the warning

> I/Gecko   ( 1276): [Parent 1276] WARNING: should already have refreshed style rule: 'ea->mStyleRuleRefreshTime == mPresContext->RefreshDriver()->MostRecentRefresh()', file /home/tdz/Projects/mozilla/src/mozilla-inbound/bug-801658/layout/style/nsAnimationManager.cpp, line 895

gets displayed roughly every second.

It works on the phones I own, but not on my PandaBoard, so this could be related to the hardware or system.

FYI: I disabled FTU, but still got such a warning. So it's not directly related to FTU.

Does it still happen if you flip the layers.offmainthreadcomposition.animate-opacity and layers.offmainthreadcomposition.animate-transform prefs to false?

And what's the "FTU app"?

I set both prefs to  false, but the warning persists.

FTU stands for First-Time Usage. It's a setup program that runs when you first turn on th eb2g phone.
