Okay, after searching the forum for possible fixes and not finding any, I'm going to post this.
Some, only some mind you, of the text in FS2_Open 3.6 and the FS2_Open_ex build is appearing in the wrong places. Namely, debriefing text appears offset down and and to the right, mainly down. However, I can only scroll down as far as the debriefing should normally go, so I cannot see all the text. I have no idea how much of it I miss, on average. I can infer from reading what I can see, however, that about one short word's worth of text is appearing, or rather not appearing, off the right side of the debriefing box.
In-mission, the support ship status text and damage-type/missile-incoming/missile-evaded text appears slightly below and very far to the right of where it should, though the little boxes it normally appears in are in the right spots.
All other text in the game works correctly so far as I can see.
I've suffered this for a few weeks now, and it's finally gotten to the point I just can't stand it anymore. Somebody tell me what's wrong, please?
