Version: (using Devel) Compiler: g++ (SUSE Linux) 4.3.2 [gcc-4_3-branch revision 141291] Qt 4.5, from qt-copy OS: Linux Installed from: Compiled sources When an external application shows something over the Panel ( a tooltip for instance ) the Plasma panel fails to redraw itself, when using the mode "Always visible". Afterwards the desktop below is visible, as if the Panel didn't exist in that area. Right clicking on a nearby area so that the menu covers the affected panel section will redraw it.
