Yes, everyone agrees on that. But games are going to keep changing
resolution no matter what you write on this mailing list, so the
question is whether there's anything that can be done to make the
users less angry when it happens. (And they will also be angry if
their games don't support changing resolutions.) Certainly KWin is
potentially in a better place to see that manual layouts and things
don't get broken than a random SDL program is... if you can't preserve
manual layouts, then who should the game developers be talking to
