Bug Description
Hello,
I am using Kubuntu 9.04 Jaunty.
Kile package version is: kile-1:
Upon launching Kile 2.1 the editor is very slow, e.g. page down page up takes longer than a second, keyboard presses also lag noticeably - it's difficult to select text. Menu operations seem to work fine, and buttons are responsive, just the text editing is very slow.
Upon launching Kile from the command line I get the following output:
kile(14771) KStatusBar:

kile(14771): Shortcut for KAction "tool_ViewPS" "ViewPS" set with QShortcut:
so at least the beginning of this seems like an error message.
Incidentally, perhaps someone can tell me how to use Kile 2.0.3, the latest stable version with KDE4, it complains that QT version is >4 naturally. Can Qt3 and Qt4 co-exist?
Thanks a lot in advance.

The long text line when word wrapped in kate/kwrite makes everything (like cursor movement, text insertion, etc.) slow. The callgrind profile (attached) suggests that it's because line repaining takes most of the CPU time.
To reproduce, open any file with a long line which would wrap onto 30-40 "view" lines.
What's interesting is that when you move cursor towards the end of the long line, repainting becomes a little bit faster.
