Can anybody duplicate this bug: https://bugs.kde.org/show_bug.cgi?id=311974 (current daily build of Kubuntu 13.04 and current VMWare Player and Tools)?
I am running a Daily Kubuntu 13.04 build in VMWare Player. On Kubuntu 12.10, with KDE SC 4.9, I normally set the panel to autohide and mouse to the bottom to reveal it. Since the early RCs of KDE SC 4.10, only Alt F1 reveals it.
