Hi Frank,
The layer rendering is asynchronous in relation to the projection
change, and layers will get re-rendered for many reasons other than a
projection change.
You might want to check out the new PanningImageRenderPolicy that is
in the OM5 repository. I think it does what you want, redrawing what
the layer has at a new location and updating the rest when it's
ready. Look in the openmap.properties file for OM5 to see how to set
it on a layer.
Hope this helps,
Don
