Desktop (icons + taskbar) moves to secondary display
 

The scenario involves a primary monitor and a DTU 1031 connected via USB and DisplayLink. Sequence of events:

1 – Open a windows session with a User1 :
DTU-1031 is on the left, Primary screen is on the right

2 - Close the windows session of the user1
3 – Open a new windows session with a User2
4 – Change position of the DTU-1031 screen : move the screen 2 from left to right
Now, the DTU-1031 screen is on the right and the primary screen is on the left
5 – Close the windows session of the User2.
6 - Open a windows session with the User1
The primary screen is always on left, DTU-1031 is on right, but the all icons has moved to the DTU Screen

I was able to replicate this on release 7.6.56 of the DisplayLink graphics adapter but not on the latest version (7.70) so it looks like the bug has now been fixed.
