Description Girish Ramakrishnan 2010-10-12 22:01:35 PDT
Bugs in Qt's AC implementation
1. When Scrolling the view, the items don't move correctly. This is reproducible using http://webkit.org/blog-files/pulse.html. Just make the view small enough and scroll vertically. The div gets clipped. 

2. For AC/plugins (see 35524), the plugin layer moves incorrectly when scrolling.

3. When clicking on the plugin, the plugin moves/increases in size.

Nit: "break;" would fit better in this context.

The scroll patch breaks youtube for me (scrolls fine but nothing renders).

Patches rebased over r69947
Comment 6 Girish Ramakrishnan 2010-10-18 08:28:54 PDT
Scrolling works after applying both patches. Can we commit them as a single patch (or split them correctly?)
Comment 7 Girish Ramakrishnan 2010-10-18 09:10:59 PDT
Err, sorry for the confusion. I had some patches before noam's patches. All good, commit in any order.

http://trac.webkit.org/changeset/69971 might have broken Qt Windows 32-bit Release

Removing bug 39121 (qtwebkit-2.1 release critical meta bug) from the list of blockers because this change won't be integrated into qtwebkit-2.1 without the other changes related to bug 35524, which already blocks bug 39121
