Bug in Total Finder Shows Permanent Image On Desktop

When I open a .dmg file after downloading a small finder window is created. This window looks like a bug. It is not useable but remains on the desktop until I relaunch the finder. This is a cosmetic bug with Total Finder because it only happens in the Finder when I am using Total Finder. I love Total Finder and would like this issue to be fixed. Has anyone else seen this issue? If so, is there a fix?

Have the same problem too. Also reported here TotalFinder and Alfred - problem with "reveal in Finder"
