I'm seeing the same effect with the Mandrake 6 distro under both fvwm and kde,
and it occurs at all resolutions.
Whenever I move a window, it develops ghost windows that are displaced about
one inch to the left, right, and top. They appear and disappear rapidly,
giving a flash effect. As soon as I let the window go, the effect goes away.
It doesn't happen nearly as often with animated GIFs.
This doesn't occur with RH6, COL22, or SUSE 6, same hardware and resolutions.
It doesn't seem to hurt anything, but it is weird looking. Haven't seen it
since the bad old days of DOS3.3. Haven't swapped the build of XFree for the
one in RH6 just to see if it's there.
I guess this is one for the people who compile kernels. What compile time
option could cause this?
