Currently what appears to be triggering the issue in metacity is that 
the window's minimum and maximum size are also changed, such that the 
window is not resizable. There's an exception to this rule if the window 
is already fullscreen-size, but the exception kicks in only for 
undecorated windows.

I'd try just removing the !decorated line from metacity, or testing this 
theory by building a version of WINE that disables decorations in this 
case, just to see if it helps.

afaik the top and bottom panels should always be in the same layer (so 
both above or both below). Elijah would know better though.

ABOVE windows can be below the panels if they don't have focus iirc.
