on adjusting monitor.preferences maximized screen buttons are covered by panel

[guiverc]

Expected behaviour

when a window is maximized; I'd not expect the window to be part-drawn underneath the panel

Actual behaviour

when a terminal/firefox (occurs all windows) is maximized; the top title bar of the window gets drawn underneath the panel is is thus difficult to use. Yes I can unmaximize using the bottom panel and if I'm very careful with mouse; drag it away from top.

this is with default settings; but it occurs when themes are changed too. HOWEVER it only occurs with certain screen orientations. I could not create this issue with only a single screen, or a conventional left-right display setup

I experienced this issue on

• hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
• hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)
  Both boxes share the same monitors; so like screen setup

Steps to reproduce the behaviour

• have displays in a TOP/BOTTOM (not left/right) alignment
• I use bottom display when seated so panel is on that screen
• maximize window on bottom screen (panel covers top of window now)

If it doesn't occur; adjust the TOP/BOTTOM displays to be reverse of what you've got.
