I wouldn't do a square thing, but it might be because it's 24bit. Might be trying to do shading on the outer edge... that's what gives it a "blurry" view when you leave the background the default you have on the theme. When I change to a black background wallpaper the icons no longer look "blurry" so I'm wondering if the shading on the edges might be what's causing it. BTW, the 8830 cannot do 24bit color (65535 colors is 16bit) so you're wasting space going that high on color depth, just FYI. Whatever the clock icon's deal with the messed up edge is is the same problem for the 2 small black triangles which indicate incoming/outgoing data transmission in the upper right hand corner of the screen.
