Certain pop-up text is stretched and zoomed when using a multi monitor setup

When playing the game on a multiple monitor fullscreen setup (mine is 3x Full HD = 5760x1080 resolution) most things are fine and are in fact great, apart from one class of text:

The yellow "pop up" type text such as

FATE Joined
FATE Completed
Quest Accepted
Quest Completed
X Unlocked

these appear stretched across the 3 monitors, and are thus very large and pixellated. (not to mention blocking the view for several seconds)
What it looks like is that the "text box" for this type of text is programmed to start X pixels from the left and end X pixels from the right, and then scale accordingly. This is fine for normal 16:9, but in tripple monitor setup it is horrendous.

There is plenty of other stuff that handles tripple monitor just fine though. Cutscenes are nicely centered on the middle one, even other pop-up text appears nicely centered in the middle one (as if that were the only monitor). So the code is "there", just needs to be applied to that type of graphic as well.

Steps:
1. Have a tripple monitor setup
2. Configure them in spanned mode to create a single 5760 x 1080 desktop
3. Launch FFXIV and set resolution to 5760 x 1080
4. For easiest demonstration of the effect, just go join any FATE and observe the "FATE Joined" text.
