When I attempt to change the background image in KDE via the control panel, nothing appears in the preview window when I select the image. When I click on the .jpeg I want to set as the background and click the Apply button, simply nothing happens. The jpeg does not display. .png files however, work fine.
Also, in the patience application, the background is usually a jpeg which you can change in the settings. However, it is now just a white background, although a jpeg IS selected. It's simply not appearing.
