You are switching to a virtual console and back to the GUI.

  "TTY, in electronic or electromechanical communications, was used to
  refer to "teletype" or perhaps "teletypewriter", but it has come to
  refer to any type of text terminal." -

  "A text terminal, or often just terminal (sometimes text console) is a
  serial computer interface for text entry and display. [snip]
  The System console is a text terminal used to operate a computer.
  Modern computers have a built-in keyboard and display for the console.
  Some Unix-like operating systems such as Linux and FreeBSD have
  virtual consoles to provide several text terminals on a single
  computer.

  The fundamental type of application running on a text terminal is a
  command line interpreter or shell, which prompts for commands from the
  user and executes each command after a press of Enter." -

By another replay I mentioned the BIOS settings in regards to enabling
bluetooth, maybe there are BIOS settings related to resume, too, that
might have impact to mouse pointer graphics behaviour. I don't think
so, but you never know.

Take a look at the release notes of possible BIOS updates, maybe a BIOS
update is related to this issue.
