Micheal,
Your suggestion is correct.
Another guy in Xorg-devel mail loop has helped me fix this issue. He
put the non A4/A8 HW acceleration in lx_check_composite() instead of
lx_prepare_composite().
I'll write a gtk+ program to trace the bug findings process.
Thanks,
Frank

You want to isolate a simple test case from eog's icon rendering ? if
so - you need to do some code reading. Personally I would follow these
steps:
* first - create a minimal gtk+ app to render a button
with an icon - I would do that by running 'gtk-demo' which
has source for you to steal.
* then include <gdkx.h> and start cut/paste/in-lining the
relevant code from gtk+/gdk/x11/ that does the image
handling
Quite possibly the problem is related to Xrender support; which we use
for rendering icons, primarily because this off-loads the alpha blending
into the Xserver (and theoretically hardware), and saves round-trips. I
would suspect XRenderCreatePicture / XRenderComposite myself.
ATB,
Michael.
