Java flashing pixel image issue?

[redsting3d]

For some reason my image flashes when i try to update a portion of the image in drawMiniMap(int x, int y), called from an outside source using imageUpdate(..). If anyone knows a way to make it so the entire image doesn't flash please let me know. It's probably a small error.

ps...view.maphash is an ArrayList<item> that stores all the data for the map and MiniMap.
