So far I have been able to get this setup which does what I was
looking for. I just dont seem to get the "Intermezzo 1" text removed:
\useMPlibrary[dum]
\startuniqueMPgraphic{mpshadow}
% BodyFontSize should be the current font size of/in the frame
mw := BodyFontSize/3;
ox := +3.5 ; % offset x
oy := +5.5 ; % offset y
bx := 2.5mw ; % bleed x (height of the shadow)
by := 2.5mw ; % bleed y (width of the shadow)
rx := 3mw ; % max. corner radius x
ry := 2mw ; % max. corner radius y
steps := 10 ; % number of shadow layers, 10 is a good value
hue := 0.015 ; % 0.02 is a good value
ycorr := 1mw ; % difference between overlay height and shadow height
for step = 1 upto steps:
part := (step-1)/steps;
xstep := bx * part ; % current part of bleed
ystep := by * part ;
crx := (rx + rx*part)/2; % current radius
cry := (ry + ry*part)/2;
% points of the rounded rectangle
xa := -xstep + ox;
xb := -xstep + ox + crx;
xc := xstep + ox - crx + \overlaywidth;
xd := xstep + ox + \overlaywidth;
ya := -ystep + ycorr + oy;
yb := -ystep + ycorr + oy + cry;
yc := ystep - ycorr + oy - cry + \overlayheight;
yd := ystep - ycorr + oy + \overlayheight;
fill (xb, ya)---

(xd, yb)---
(xd, yc)...

withcolor transparent(1, hue, black) ;
endfor;
