When you enable auto-hide for panels, they do not auto-hide but either stay in front or behind the window. No hiding is happening. Reproducible: Always Steps to Reproduce: (Because of the stupid translations, I only can guess how the stuff is called in English.) 1. Click on the cashew of a panel (e.g. the one where the standard task bar is is in), 2. In the opening bar, click on “Further Settings”. 3. In the opening menu, click on “Auto-hide”. 4. On that screen, make a window full-screen. 5a. If the panel still is visible: Notice the panel not auto-hiding. Click on the window to get it to the front. (Maybe this only happens when the focus was somewhere else before. In that case just switch to another window and back.) 5a. Try to make the panel visible by moving the mouse to the border of the screen it is on. Actual Results: In no case does the panel actually hides itself. And if it’s behind a window, it’s not reachable anymore. Additionally, if it’s before a window, and doesn’t hide (I had that happen here, but it’s harder to reproduce.), the window title and part of the menu are not clickable anymore. Expected Results: Panels set for auto-hide should hide, like before. Meaning, they slide in when out of focus, and slide out, when you move the mouse to their border. This is new since 4.6.0. I did not have that problem with 4.5.5.
