Sorry for not stating it clearly, appreciate the quick response.  It's b
- application doesn't render correctly using the imlib2 library.  I
attached the test program as an example.

I tried turning off the cache, both in the small test application and in fluxbox (src/FbTk/ImageImlib2.cc), but that doesn't make any difference.  I'm typically doing this under VNC, it works fine on mwm and the Fedora-standard gnome/metacity desktop - I only see this problem using the testcase on fluxbox.

Yes, for no real good reason.  It seemed like there could be an issue
with caching, so this seemed like something quick to try.
