When loading very large rasters the image does not always get drawn correctly. Sometimes the left most portion of the image gets drawn twice or more to cover the right most part of the image.
This appears to be true for several different raster formats (I tested Mr. Sid and Geotiff). You can reproduce this result by creating an image that is 10000 pixels wide and 5000 pixels high and fill it with a simple gradient (green to red is what I used) and save as a tif. Then load up and and zoom in on a thin strip covering the full width but only a portion of the height.
