Created attachment 66888 [details] Plasma config files Version: unspecified (using KDE 4.7.2) OS: Linux In a laptop+external display configuration, the laptop panel has an "auto-hide" setting in the upper side. When I press Fn+F7 on the laptop, or otherwise allow KDE to manage my screen settings, the panel on the laptop will no longer work as "auto-hide" correctly, and instead it will behave like there are two panels: 1. one permanently visible, with the system tray broken (only some of the icons appear) 2. one that works correctly and shows up when I activate it. Number 1. is the one bothering, and playing with the visible/auto-hide settings doesn't help. Restarting plasma solves it. Reproducible: Always Steps to Reproduce: -On a laptop or laptop+external display set-up a panel with autohide feature. -Play with Fn+F7/F8 or otherwise trigger the KDE randr managing functionality. Actual Results: Get broken panel number 1. as described above. Expected Results: Only get the original panel. The movie at ftp://cetaura.com/evil-twin-panel.ogv shows the problem. Watch for the upper right panel. It is always visible with a broken system tray. When moving the cursor to the edge it will appear in the foreground with a working system tray. I'll also attach the plasma*rc files from the kde config directory. This bug seems somewhat similar to #211619 and I feel it's even related with #279528.
It's ok on my KDE 7.4.7
4.7.4* typo (In reply to comment #1) > It's ok on my KDE 7.4.7
I think I can confirm that there's some sort of duplication, the widgets on the desktop are duplicated, for example I can see the "temperature monitor" twice before restarting Plasma. The currrent version is 4.7.4.
I haven't seen this problem for a long time. Bug video reuploaded: https://www.youtube.com/watch?v=blvm7uMWPY4&feature=youtu.be
