When I use the "Opaque Window Moving" option, I get a very slow
update on the screen, resulting in several seconds of lag before
the moved window settles in the final position. There are also
large ugly artefacts on the screen during this slow motion.

I noticed the problem in fluxbox version 1.1.0 and I just tried
a fresh git-clone of January 1, 2009, and the problem remains.

My system is a quad core amd64 phenom 9550 with 4gb of ram and a
radeon hd3650 graphics card. Kernel is 2.6.27.7 and the distribution
is slamd64 12.1.0 (64-bit slackware). The screen is 1920x1200 @60Hz.

The ugly artefacts are visible with windows as small as 200x200,
and the lag is clearly noticeable at 600x600. However when I tried
fluxbox in an Xnest window, the problem disappeared completely.
So opaque window moving works in Xnest, but not in the root window.

Can this be fixed? Is there som hidden configuration I can tweak?

Regards,
