Now. Neal ManBear. Was that a coincidence or did you know something?
I did not say, "Try this." I said, "Install shutter." See the difference? The former would be a suggested solution. The later was a solution. In other words, of course I know something.

Again, I don't see how Shutter had anything to do with it. So, it must have been IOManager. Was it the problem all along? Or, did I (we) unwittingly do a combination of things that fixed it?
Thanks
IOManager? You mean lomanager. That is a lower case "L," not an "I." You are the second person to try to claim that lomanager did something to your icons. Let me make this perfectly clear, lomanager has nothing to do with your icons. Not one thing! It has one job only, the management of Libre Office.
The culprit was shutter. Its last update had changed permissions on icons. (From the shutter people.

) Installing our newest update resets the icons permissions. In other words, a new RPM was packaged with the resetting of permissions as a part of the package.
