Hi,
the low resolution of the point symbols is (for us) really a problem. I assume that somehow the selected resolution (in my example 300dpi) isn't applied to the point symbols. And/or too much anti-aliasing is used or JPEG compression.
Best, Markus

This problem occurs because QGIS is using the same point symbol it does for the map canvas, but scaling it up. If your symbol is the default circle, the symbol will be ~7 pixels tall, regardless of the composition resolution. Fixing this will probably require the addition of an extra function to get the point symbol as a variable or high-resolution pixmap.

If you set the symbol scale in the map composer from 0.5 (default) to 0.1 the point semm to be well draw but in the problem occours ever in the legend.
