Created attachment 114065 [details] screenshot showing the problem When opening the bluetooth kcm through the bluetooth systray icon its window size is always too small to fit all content. Instead scroll bars are shown. That's especially annoying, because the scrollbars hide the buttons for adding and removing devices. Opening the bluetooth kcm using system-settings works fine, as the systems-settings window remembers its size across openings, while the standalone opened bluetooth kcm window doesn't. The attached screenshot shows the problem running KDE under X.org with a DPI of 109 (not sure if that's important).
