Version: (using KDE 4.3.1) Installed from: SuSE RPMs When I start downloading a file, for example to open it with okular, a file transfer notification dialog is shown in the lower right corner. However one does not see the dialog directly. First a shape with the form of the dialog is shown filled with garbage. Then the shape is filled with the correct contents. It appears as if first just uninitialized memory is used to print the dialog.
You can see the bug in action in the video posted by Aaron Seigo in his blog at 0:44. http://aseigo.blogspot.com/2009/09/dropping-remote-content-and-wallpapers.html
this is probably a qt bug and not a plasma bug
2 possible reasons: a)the view that is not focused on the real widget for a while b)xorg video driver bug, and in this case is upstream
Another possiblity is that a widget is not correctly filled with a background color. For example I've seen this when a pixmap was not initialized with a color.
