Comment 4 for bug 533271

I've tested the content of the branch. I think that you should change for both Radiance and Ambiance themes this setting:

style "panel" {

 xthickness = value
 ythickness = value

 bg[NORMAL] = "#faf7ee"
 bg_pixmap[NORMAL] = "panel_bg.png"
        engine "murrine" {
            roundness = 0
        }
}

xthickness and ythickness should have a value of one for the best appearance.

For the Ambiance theme this was set to 0 and 0 (x and y thicknesses). For the Radiance them it was still 4 and 0.

Still needs some little tweak.

Cheers
