Comment 3 for bug 1798490

This is actually not an issue specific to tutorials but happens with every document if you have "Save and restore window geometry for each document" in Preferences -> Interface --> Windows enabled and the location stored in the document does not match your monitor set-up (specifically if the coordinate (0,0) is outside of the visible desktop area, which is the case for you (it's in the upper left corner of the combined screen area).

There's a fix for this in master. I'm afraid it's unlikely we'll be able to properly fix this for 0.92.x, though.
