936332 - Overscroll image on OS X is a different size than actual page when page is zoomed in/out

Status: RESOLVED INVALID

(Core :: Widget: Cocoa, defect, P2)

Description

[Jeff Muizelaar [:jrmuizel]]

I see this on OS X 10.7 when overscrolling on tbpl.

Is the page zoomed in or out by any chance? Could you attach a screenshot please? Thanks!

Comment 2

[Jeff Muizelaar [:jrmuizel]]

The page was zoomed out. It's hard to capture a screen shot because it's only visible during overscroll. The overscrolled image is a slightly wider version of the tbpl page.

Great, thanks! The main issue around pagezoom was fixed by bug 932013 but we seem to be dealing with a rounding problem here.

This probably also affects swipe animation.

Yes, confirmed with latest nightly on 10.9 that this effect can also be seen while swiping.

Jeff/José: do you have the option View > Zoom > Zoom Text Only disabled? (which is not the default)

I am able to reproduce this bug with that option disabled.

I just tried this again with a new profile and "Zoom Text Only" is disabled by default (browser.zoom.full = true). 

This issue is only reproducible in some zoom levels. 

STR:
1. go to https://www.mozilla.org/en-US/
2. zoom in one step with cmd+
3. overscroll the top of the document

Repeat those steps until finding a zoom level where this issue can be seen. I can provide a video of this issue if necessary.

Oh sry, I got confused by the default value (it's false in all.js but firefox.js overrides it to true).

I can reproduce it with those STR, only when browser.zoom.full = true

The code in question here has been removed in bug 860493.
