Description

When I put many objects in the map composer the rendering became very slow and I shift the objects with very difficulty because they do not follow the movements of the mouse.

How many is "many objects"? Are you using render or cache mode to display the objects?

Just the map, a label, a scale, a legen and an image but it seems not depending by what I load on the map canvas and by its extension. If I use recatangular mode all is ok, with cache mode the rendering became slower and if I use render mode it is very difficult move teh objects.

I'm marking this as a defect, since this is fairly normal behavior. The solution would be to not re-draw the object while dragging, and just show its outline with a dotted rectangle.
