X11 flicker (using imagemagick::animate)

[Darren Weber-4]

Does anyone see a lot of flicker and poor interaction behavior when using the animate tool from ImageMagick?

It's almost useless on 10.5.8, with XQuartz 2.4.0.

It looks like ImageMagick builds against MacPorts X11 libs, not the XQuartz installation:

$ otool -L /opt/local/bin/animate

Right, that's per MacPorts policy to use internal libs rather than system ones where practical.

The MacPorts libs are actually newer than the ones in XQuartz 2.4.0.

My guess is that animate uses normal Xlib calls to render its images.  Is there an option to use the RENDER extension instead?
