don't ask me because i haven't got a clue. it looks like a problem with that hacked component you're using.
Yea that's a problem, because it uses aero transparency, I don't know how to avoid this..
It uses this to enable-disable glass i think:
function on_paint(gr) {
// Apply Glass Effect
if(glass_enabled) utils.CreateGlass(Foobar_hWnd, -1, -1, -1, -1);
if(opt_bg_alpha=="255") {
if(glass_enabled) utils.CreateGlass(Foobar_hWnd, 4, 4, 4, 4);
} else {
if(glass_enabled) utils.CreateGlass(Foobar_hWnd, -1, -1, -1, -1);
}
if(glass_enabled) {
gr.SetSmoothingMode(2);
gr.FillRoundRect(0, 0, ww-0, wh-0, 3, 3, RGBA(10,10,10,10));
gr.FillRoundRect(0, 0, ww-1, wh-1, 3, 3, RGBA(10,10,10,20));
gr.FillRoundRect(1, 1, ww-3, wh-3, 2, 2, RGBA(10,10,10,80));
gr.DrawRoundRect(2, 2, ww-5, wh-5, 1, 1, 1.0, RGBA(255,255,255,30));
} else {
gr.FillSolidRect(0,0,ww,wh,RGB(0,0,0));
gr.FillSolidRect(1,1,ww-2,wh-2,RGB(120,120,120));
}
}
