I have this (or a similar) issue too on an ARM (xscale) based platform. I have found that for me the FLTK images display correctly if they are an even number of pixels wide. I have been lazy and just ensure that all images I use are like this.
Note that this applies to the actual number of pixels printed on the display, transparent pixels don't count. For example, if you have a gif that is 30 pixels wide, but the left hand row is transparent, that's only 29 pixels so it will distort.
The kind of distortion I get is that vertical lines get skewed to diagonal and colours sometimes turn to black. I have not looked into why this happens so far. Hope this helps,
Darren.

Hi all,
I'm working on a project based on FLTK library to create an user
interface using fluid. For development and test I'm running the application
on linux with X library.
The target is based on AVR32, and I'm using nano-X+nxLib on FLTK.
The problem is that when the application is running on the target, all the
image (jpg, gif, xpm) are distorted.
The only kind of image that work good are the ppm images that unfortunately
don't support the trasparency layer.
did anyone have same experience? did you solve it? Any suggestions?
Thanks
J.
