758655 - Fix motion blurring on scroll

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect)

Description

[Ian Barlow (:ibarlow)]

The motion blur we use when scrolling quickly is pretty neat, except when scrolling stops and you're stuck with a blurred page, sometimes for upwards of a second or two. 

We should find a way to leave that "blur mode" as soon as you either slow down scrolling or stop scrolling.

Sounds like bug 757039 which was fixed on Nightly two days ago

Is there a specific page you were having this problem with?

The motion blur is just the low-res screenshot that replaced checkerboards a while ago, isn't it? There's probably already a meta bug somewhere about reducing checkerboarding.

It seems to be happening on www.smashingmagazine.com, on today's Nightly on tablets

www.smashingmagazine.com is slow to paint because of shadows. Here's what seems to be happening. 

Because the page is slow to paint the lowres screenshot takes a very long time to take. Currently we'll take the screenshot about every 5s and this can cause the low-res content to stay on the screen because we're busy taking the screenshot and can't get around to regular painting.

A couple of things will help here. We're working on making the screenshots have less impact and happen at better times (bug 755070). Second we can make the shadow bluring more efficient (bug 758825)
