Timage & Linux slow repaint after moving a window over etc

I have an application that displays a picture in timage as the only
object on the form. When it switches from foreground to background or
another window is dragged across, It repaints slowly maybe 1/4 at a
time. This is true for even a small window.

This is with Fedora13 on the gnome desktop. The same program is snappy
on windows.

Should I display the picture in another manner for Linux???

thanks

Is it a huge picture that is stretched to be scaled down by chance?
I've haven't had that problem on Ubuntu at least

it is 3200x2400 and stretched to scale down. I don't see the problem
in windows,, but timage is much closer to the api there.
