Maximize window makes window disappear

[harald]

- dual-head
- monitors on top of each other
- maximize window on lower monitor

- lower monitor is primary, don't know whether that actually makes a difference

=> window disappears, in shift-switcher only title-bar of window appears

screenshot: maximzed firefox on lower screen, seen in screen's menu bar

here is the output of xrandr:
Screen 0: minimum 320 x 200, current 1920 x 1968, maximum 4096 x 4096

[Brendan Donegan (brendan-donegan)]

The behaviour described isn't quite what I get. What happens is that the window that was maximized in the lower monitor doesn't quite maximize all of the way. There is still a significant part of the bottom screen which just shows the background. Everything else seems to work okay though. A screenshot is attached to illustrate.
