 Using qgis Trunk 1.4.0-80 on Windows XP and Grass tools plugin 1.0.2-2
 rendering of GRASS rgb composites (created with r.composite) in the map
 canvas takes very long. After every zoom or pan the extremly slow
 rendering starts again. This bug seems to be related to
 https://trac.osgeo.org/qgis/ticket/1816).
 In qgis version "Metis" 0.11 the performance of rendering GRASS rasters
 and composites was very fast.
