Using the Kali Linux

Hi there, I current have three known issue with Kali Linux GUI

  1. When copy large number of files - doesn't show the progress whatsoever. I got the false impression that the files has already been finished copying
  2. Opening of existing folders, it will only show up as dots on the folder.
  3. Recently, I was unable to press 'Open Terminal' on my desktop, all my existing terminal will go missing.

Is this a new installation or have these issues suddenly occurred on a working system?

What is the hardware platform?
