After launching a PSM session to a Windows 2012 or Windows 8 (or above) system and using it for a few minutes the mouse cursor may disappear or be corrupted. It may also change to an unexpected cursor, such as a 'hand' cursor, i-beam and not transition correctly to the different icons.
Disable the mouse pointer shadow for the account on the target PSM system.
This can be done from the Control Panel | Mouse settings | Select the "Pointers" tab | Ensure "Enable Pointer Shadow" is not selected.
Alternatively this can be done via a registry modification. This option is part of a bit mask, further information on the required masking may be found at https://technet.microsoft.com/library/cc957204.
After the registry change is made the user would need to log off and log back on, or restart the computer to apply the changes.
