Partial canvas redraw

When panning a map, Qgis blanks and redraws the entire canvas. I think this is a big issue, as the user looses all sense of track with the map. MapInfo only redraws the new canvas area while retaining the panned area. That is a much better transition, and probably faster.
I hope that this issue is not reduced to low priority, because zooming and panning in Qgis is really a weak spot that would compel some to give up on Qgis. At my work, I replaced MapInfo with Qgis on my colleagues computers, and the most significant feedback I got was the low speed canvas handling, thus loss of track.
