the Qt port of WebKit
- 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.
