After the sessions menu has been opened once the panel does not hide any more when autohide is enabled. Downstream report is at https://bugzilla.novell.com/show_bug.cgi?id=764310.
Further info, I was able to clear this bug by changing the panel mode to deskbar and then back to horizontal. This worked a few times but is no longer effective. For me it was a click on the Action button for shutdown, etc, that killed the autohide.
Further info, reboot this morning gave restored autohide. clicking on Indicator plugin, action buttons or radio tray removes the autohide function. Switching to deskbar and back to horizontal cured this once but now it's stuck, until reboot I guess.
(In reply to comment #2) > now it's stuck, until reboot I guess. Hallo, try runnung the "xfce4-panel -r" to fix the broken autohide, it works at least for me.
