If I open a window in fullscreen mode, and hit <Alt>-<Tab> enough times to cycle back to the current application, the xfce panel will appear above my application window.
Steps to Reproduce:
1. Open two applications (terminal and firefox)
2. In one window, turn on fullscreen (Alt + F11)
3. Hold down the Alt key
4. Hit the Tab key enough times (should just be 2 times if you only have 2 apps open) to select the currently open application.
5. Release the Alt key
6. The xfce panel will now be overlayed over your application.
Application should still be in fullscreen mode (i.e. panel should be hidden)
Should be fixed in svn, both branches, revision 22170
