Hi Prageeth,
I had a look at the old-new pictures, and they look the same to me..
Can you be a bit clearer on what you mean with 'better'?
I don't know straight off why you would not get a pgm though, although
if you got it from a RGB16 than that would have been in error, so the
newer version is correct in that sense.

Hi All,
We are in the process of upgrading a legacy DirectFB-0.9.24 system to
DirectFB-1.2.8, the later being built using buildroot-2009.05.
However, the PNG test image looks better on the legacy DFB than on the
newer version!
On using IDirectFBSurface::Dump(), the destination surface for
RenderTo(), and the final window surface to which Blit() is done, are
both found to be same using legacy and new DFB. However, the primary
layer’s surface seems to differ as in attached ppm files. Moreover,
the legacy version dumps a pgm file also.
The DFB configuration of both systems were found to be same as
attached. There is no hardware acceleration involved. Frame buffer
settings given by fbset were also found to be same. However, the older
2.6.14.2 kernel had to be retained so that various device drivers
could be reused.
Hope using an older kernel need not be an issue. Any suggestions or
debugging tips would be of great help.
Thanks,
Prageeth
