598111 - Blurry text on some pages when zoomed out in Fennec

Status: VERIFIED FIXED

(Firefox for Android Graveyard :: Panning/Zooming, defect)

Description

[Matt Brubeck (:mbrubeck)]

Attachment: screenshot

Steps to reproduce:
1. Open Fennec in portrait orientation (ctrl+shift+q on desktop)
2. Click the "About Mozilla" link at the bottom of the about:home page.
3. Double-tap anywhere to zoom in.
4. Double-tap again to zoom out.

Expected results: Normal rendering
Actual results: Blurry rendering (see attachment)

I can reproduce this consistently in a desktop GTK build from the following revisions.  Sometimes the page is blurry after step 2; it is always blurry after step 4.

Is this a dupe of bug 597336?

I also get blurry text if I open https://bug596895.bugzilla.mozilla.org/attachment.cgi?id=477094 and then click on <a href="#">test 1</a>.

In addition, the tap highlights are then drawn as if the page had scale=1.0, even though the page still appears at the default scale=1.5.

_scale should only be set in _setScale

Another problem is that onLocationChange is *not* the place to get ready for the next pageload. Resetting the scale is now done in pagehide.
