Yes, but what is that ? dispwin does nothing unusual - it creates
a window and draws colors on it, just like any other application.
The only slightly unusual thing it does is set the VideoLUTs, but
this happens some way through the normal dispwin operation
(when it says "Darkening screen" "Lightening screen" "Restoring screen"),
yet you say the display blanks out as soon as the window
appears.
Not also that by default it sets the contents of the VideoLUTs for
every test patch of dispcal.
So what is causing this ?
