3dvision not working with two screen display config

[lefuneste01]

I use a two screen display configuration. 1st screen = Benq 3DVISION XL2420T 24" 1920x1080, 2nd screen= an old 19" 1280x1024 without 3D.

I used the second screen to display shkval and MFD, in 2D, total res = 3200x1080.

It works well with 1.2: cockpit view in 3D vision on 1st screen and MFD&shkval on 2nd screen. It works also in non 3dvision mode with 1.5b, but when activating 3Dvision the total display (cockpit+MFD) is "packed" on the main screen, and horizontally streched to fit the 3200 pixels into the 1920 resolution. Going out of 3Dvision mode restore the screen layout.
