So, there seems to be some issue with the first width/height computation ;
something like this helps:

-int width = min(pBox[i].x2 - pBox[i].x1, tileWidth);
-int height = min(pBox[i].y2 - pBox[i].y1, tileHeight);

+int width = min(pBox[i].x2 - pBox[i].x1 - tileWidth, tileWidth);
+int height = min(pBox[i].y2 - pBox[i].y1 - tileHeight, tileHeight);

Otherwise you start the 2nd copy (first one in the while loop) with the full
tile size, and this can be bigger than the total size.
