Icon on desktop goes transparent after deleting another icon

Everytime i delete an icon on my desktop, another one becomes transparent I've been looking what was the problem couldn't find anything.

Are you saying you now have several transparent icons on the desktop? What happens if you click an empty part of the desktop? Do the icons go back to their original look or do they stay transparent? What happens if you restart the computer?

You could try rebuilding the icon cache.
