I noticed that reducing the color depth to 16 bits for the bitmap,
the problem does not occur any more.
Anyway the missing pixel are actually "white", but I noticed
that some of the missing pixel where in the middle area of the bitmap as
well.
I'll try to make further checks.
Thank a lot,
Casadei Franco
