Version: (using Devel) qt-copy, kde from today's trunk. If I make a window bigger, the content of it is resized, but the area itself is not, until you switch to another application and back. This is e.g visible in applications, where the layout of the widgets depends on the width of the window, like in Konqueror. E.g. if you enlarge the window only by a few pixles, the right vertical scrollbar will be only half-visible. Window decoration buttons are not moved either (well, the area where you have to click moves, but the buttons are draw into the old place), making it impossible to click on them. Maximize works. Shrinking of windows works.
