By elimination:
- does not arrise in my machine whith the image

- it arrise only with image with an alpha channel
- only when running icewm or fluxbox but not running kde and gnome
- only on linux and macosx

The interection of all this fact point to X. But we are clueless to
help. How can we debug this kind of problem ?

I suppose I could wait after freeze.
