This is the key to the problem.
Using different fpc version, different Lazarus versions, different 
Ubuntu version won't help.

When drawing images on gtk, lazarus has to use the same pixeldepth as 
your X server. gtk won't do any conversion, except for 32 bit. Usually 
drawing 24 bit images on 32 bit X is also OK.
In your case not. The only thing you can do is reducing the pixeldepth 
of your X server.
