: I'm running FLTK 1.1.7, Nano-X 0.91 and NXLIB 0.45 on a Colibri PXA270
(ARM
: architecture)

eg incrementing or decrementing the red slider by 1 causes a dramatic change
in colour.
I'm wondering if by chance the RGBA is endian-swapped
and ending up GRAB or something like that... Is the ARM
running big-endian?
If so, perhaps nano-X isn't in fact running properly.
Otherwise, NXLIB is likely at fault, start perhaps
with some inspection and debugging in XOpenDisplay,
where the color format is detected. There may also be
issues with images only, versus other color draws.
We need to ascertain exactly what sorts of things are
being drawn (images vs rect fills vs blits) and
go from there.

Greg
