1012496 - new tab page layout inconsistency 9 tiles or 6 tiles

Status: RESOLVED INVALID

(Firefox :: New Tab Page, defect)

Description

[Asa Dotzler [:asa]]

Latest Mac nightly (retina display)

Open a new tab page and then press and hold cmd + p to see the page jostle between 6 and 9 tiles. There's some kind of timing issue there, I think, perhaps during the sizing or positioning of the search box which I can see visibly flicker when opening new tabs.

<AsaDotzler> my nightly mac build is switching between 6 and 9 tiles seemingly randomly.
<AsaDotzler> when creating a new tab
<AsaDotzler> if I open a dozen or so, it's alternates pretty consistently,  but when I switch back to the previously opened tabs, they're all 9 tiles
<AsaDotzler> there's something flickering in the left of the search box, looks like a button style for a tiny fraction of a second.
<AsaDotzler> if I open a series of tabs quickly, then I get 9 tiles more often. If i open a series of tabs slowly, I get 6 tiles more often.
<AsaDotzler> size or position of search box is changing some tiny fraction. I can see it simply reloading a new tab page
<AsaDotzler> simpler demonstration: just hold down command+r for a few seconds and watch the various renditions of the new tab page.
<@gavin>	 AsaDotzler: can you file that and cc :adw / :mardak?
<AsaDotzler> Sure!

Also seen occasionally on my Win8 x64 box running nightlies - but never with enough of a pattern for me to speculate on what might be causing it.

I'm not seeing this anymore, are you still able to reproduce it?

Not seeing it with the same steps to repro so either it's fixed or diminished. I'm OK with resolving this since I can no longer repro with these steps.

Sounds good, thanks.
