If you look at the first screenshot, you can see the effect appearing when the window's vertical size is approximately 16px less than the screen's vertical height.
I tried with Total Commander 7.50a, and foobar2000 v1, and they do use the whole window surface when maximized; also when the screen panel is hidden in a corner, so the window has all the screen to itself. I'm using the default Ubuntu 9.10 window manager..
Anyway, this is a separate problem than the one you originally reported in the bug Description. Please file a new bug. IIUC it should be named, for example, "foobar2000: Application does not use the whole window surface when it is maximized".
TBH, it's a bit confusing. Your maximized window has no borders, and it's difficult to tell where the window ends.. especially since the 16 pixels at the bottom are all white. I mean, if there would have been some garbage in that region, like in the other screenshot, then it would be clear.
