Same here, on a Nexus 5.

Using the Google search results:
* Pinch zoom a little
* Pan to the right side
* I see blurry text and usually a "line" probably showing the edge of a tile

Matt - Any ideas?

Comment 8

[Nick Schubach]

I don't need to zoom at all, it seems to happen regardless

These patches weren't meant to have any effect for android, I'll take a look.

Attachment: Fix

Looks like I missed the #define so we weren't calling SetIgnoreScrollFrame for android. nsLayoutUtils::UsesAsyncScrolling covers all the cases we need without #ifdefs everywhere, so switching to that.

It did! Not sure why the push url's didn't end up here.

The regressing change isn't on aurora, so I don't see how firefox33 can be affected by this bug.

Ok, thanks for checking.

This must be something else, can you reproduce on Google in particular? If not, let's set the flag correctly.

On Aurora 33.0a2 (2014-08-19)
Landscape mode only:
Go to cnn.com and scroll to the bottom of the page, or
Go to Settings -> Mozilla -> About Aurora -> Support and scroll to the bottom of the page.
