Version: (using KDE 4.3.0) Installed from: SuSE RPMs When I switch to a virtual desktop and right-click on a taskbar entry with the right mouse button, a popup appears showing me the std. window actions (To Desktop. move, resize, ...close, ...) The first time this popup opens, it is as wide as the taskbar entry, but the content (the window action entries) have a different background than the popup background itself. This looks wrong. See attached screenshot.
