Windows go below when "Always visible" is set and using multihead. Only when panel on the screen edge before transition to second monitor. Reproducible: Always Steps to Reproduce: 1. Place panel on the screen edge before transition to second monitor. 2. Maximize window. Actual Results: Maximized window is under the panel, see screenshot. Expected Results: Maximized window is beside the panel.

I have the exact same issue. Fedora 17 x64 running dual monitors on an HP 8440p (primary via Display Port, internal panel beneath). I only have panels on the top screen (Display Port), maximised windows go behind the bottom panel regardless of "Windows go behind" setting. Windows dragged to that screen from the internal laptop panel also go full-height and the bottom part goes behind the screen.
Are https://bugs.kde.org/show_bug.cgi?id=302282 and this bug duplicates?
No, for me at least the bug is different. My panels are horizontal, on the top screen. Steps to reproduce : 1. Start any application (position window on lower screen, the laptop screen, no plasma panels) 2. Drag window to external monitor. This display has a panel top and bottom. Results: Window goes full height automatically, top edge correctly stops at the upper panel, however lower edge goes behind the lower panel. Incidentally this behaviour is the same if a window is maximised on the external screen.
Not sure whether anyone has had a chance to reproduce this bug, it is one of the few annoyances on an otherwise excellent distro. Attached is a screenshot (scaled down) of the issue with a maximsed window. As mentioned before, windows dragged to the external screen maximise vertically behind the panel but remain the same width, those maximised do the same but also expand in the horizontal axis.

Still happening in Fedora 22. Monitor setting: two monitors, one on top of the other. External monitor is the upper one, laptop monitor is the lower one. I place a taskbar (default panel) on the bottom of both monitors. On the laptop monitor this works fine, on the upper monitor windows maximize ignoring the panel and going below it, regardless of any settings. If on the upper monitor the panel is placed at the top of the screen rather than the bottom, things maximize correctly.
Can confirm still happening, other distro: openSUSE Leap 42.1 plasma version 5.4.2
Still happening in Plasma 5.5.3. Btw this seems to have been fixed in Plasma 4...it worked properly in the last several versions I'd used. Could someone update the product and version fields to reflect that? Or does this need to be refiled for Plamsa 5?
Oops, nevermind, there already is a Plasma 5 version of this: 348043
