I know it's late, but I've been busy with other things.
It still suffers from the same problem I wrote in a private mail
to Ville on 2006-05-24:

This shadow is more likely a shrinked picure of a previous frame.
Should I make a screen shot to show this ?
I tried to add some debug fprintf, but they did not show erronous values.
Values from start of matroxDoBlitTMU() :
f(0,288,36,216,10,9,1,0)(0,288,36,216,10,9,1,0)F(0,576,0,576,10,10,0,0)
fprintf(stderr,"(%d,%d,%d,%d,%d,%d,%s,%s)",
sy,sh,dy,dh,
w2,h2,
filter ? "1":"0",
mdev->blit_deinterlace ? "1":"0");
