Please follow the QtWebKit bug reporting guidelines when reporting bugs.

See http://trac.webkit.org/wiki/QtWebKitBugs

Specifically:

  - The 'QtWebKit' component should only be used for bugs/features in the
    public QtWebKit API layer, not to signify that the bug is specific to
    the Qt port of WebKit

      http://trac.webkit.org/wiki/QtWebKitBugs#Component

  - Add the keyword 'Qt' to signal that it's a Qt-related bug

Reproduced with Qt 4.6.3 against r55658.
Wow, that's pretty bad.

Stumbled upon the same issue.  From the info that the Web Inspector timeline gives, "Painting" takes ages, from tens of seconds to a minute.

I managed to track this down and work around it by removing a particular "position: absolute" CSS line on a nested div in my code, though there's apparently a weird bug lurking somewhere that happens (or so I hear) only on the Qt port of WebKit.  Incl. Qt 4.7 tech preview.

=== Bulk closing of Qt bugs ===

If you believe that this bug report is still relevant for a non-Qt port of webkit.org, please re-open it and remove [Qt] from the summary.

If you believe that this is still an important QtWebKit bug, please fill a new report at https://bugreports.qt-project.org and add a link to this issue. See http://qt-project.org/wiki/ReportingBugsInQt for additional guidelines.
