Dmitry's problem is that if he does maximize, quit and relaunch with KAtomic,
the central widget does not resize at all after the relaunch and looks yuk. In
that particular case, KAtomic gets only one resize event form the startup of
main window, which KAtomic ignores because it is a "pending" event.

This is great :-) ... however ... :-(

IMHO the double resize in KDE4 main window startup is the main
problem and could affect every KDE4 application that has a large
amount of rendering or painting to do when it starts up.

I checked back with KDE3 (3.4.2 specifically) and it triggers just *one*
resize event when the main window starts up.  So I think this double
resize in KDE4 is a *bug*.  Could you ask lubos about it, Aaron?

All the best, Ian W.
