The first line only takes up 50% width on a 1280x1024 resolution. Something is forcing that last word to go onto a second line for some reason...
I used to have x at 0.47, then I changed it to 0.25 and it still did the same thing.
Attached is a screenshot at 1280x1024 resolution.
Edit - Just tried with x = 0.0, and it does exactly the same thing, just on the very left hand side of the screen.
