Version: unspecified (using KDE 4.5.1) OS: Linux When i login the first time (machine startup, with and without autologin), plasma show me an empty transparent plasmoid/window on my desktop. I can click inside this window to show desktop menu. Logout/login again fix issue. Removing plasma*rc fix issue for some times and after, bug come back. Reproducible: Didn't try

Same problem here. Mine appears in the top left corner of my screen. The geometry of the window is 1280x720.
Same with Kde 4.5.3... It's really a bad bug, can't deploy Kde 4.5 ... :(
