Screen blanking with multiples screens on targets hosts

Hello,

 

We installed many GTMPC licences and discovered a quite important security issue:

 

while screen blanking works fine when the target (desktop) has only one external screen, when such similar Desktop PC   has multiple screens (up to 6) connected to it then only the default screen is blanked...

 

Hence when other people stay in front of the target PC they can observe all the operations taking place on all the screens aexcept the default blanked screen. QUITE BAD situation indeed.

 

We are running Dell optiplex systems with standard DELL screens.

 

Any help is very very welcome as the confidentiality of the sessions are nearly impossible to achieve.

 

help would be very much required.

 

Is there a fix planned ? which release ?

 

Thank you very much.
