When people say I don't want my DM to roll behind the screen because I don't want him to fudge that is a trust issue. Because you don't trust him not to fudge.
There are lot of reasons a DM uses a screen besides fudging he may use it for the info on it or to hide his notes or hide certain rolls that have nothing to do with combat.
If your agreement is to let all rolls stand then it shouldn't matter where the DM rolls.
Look each group has to decide for their own group and if the DM and players want to roll in the open that is fine. What I have taken from a lot of posts I have read on this over the years is the attitude that if you roll behind a screen it is because you are fudging. That is what bugs me that and the attitude that some how letting the dice fall as they will is the correct way to play DnD and if you don't you are not really playing DnD the way it was meant to be played.
Oh, I have no problem if you want to play behind the screen. I just don't see the need for it personally. If you're not going to fudge, then why roll behind the screen? The only reason for the DM to hide rolls is to fudge rolls.
I don't enjoy games where the die rolls are fudged. It's not a trust issue at all. I KNOW that the DM is going to fudge hidden rolls. That's the whole point of hiding rolls (other than maybe rolls where knowing the result ruins play - such as searching for traps).
And there's absolutely nothing wrong with that. Not my preferred style of play, but, certainly one I've seen done and seen done well. On purely practical level, I roll in the open because it's faster. The players know automatically if something is a success or not, so, they can move on without the step of me telling them anything, by and large.
It tends to keep the pace of the game a bit higher, again, IMO. Which, again, IMO, is a good thing.
