After I updated KDE to the latest 4.10 build from Kubuntu repositories, the Pager Widget is sometimes invisible. The right click popup menu shows as normal, and i see empty space when I edit the panel. I tried to move it, create another, disable and re-enable desktop effects, change theme, still nothing happens. It shows if I manually add a desktop at every boot up. I'm using Oxygen-Transparent theme. Reproducible: Sometimes Steps to Reproduce: 1. Boot up to KDE Actual Results: The pager widget is invisible if I don't add a new desktop Expected Results: The pager widget shows normally NVidia driver 310.14 KWin and compositing enabled Oxygen-transparent theme KDE 4.10.0
