Antialiasing problem with center-aligned text

I'm having a problem where my text gets an anti-alias effect if it's alignment is set to center. It only shows up in Fullscreen mode.

The font is a bitmap font set to 12 pixels and it displays as intended in 720p resolution while being Horizontal center-aligned and also in 1080 while NOT Horizontal center-aligned.

I don't know how would I fix this beside never using center alignment for (some) text.

Link to the test project:

My guess is depending on the width or height of the text the center is at half pixels. If that is the case, increasing/decreasing the size by 1 pixel should fix it.

I tried increasing/decreasing width/height/both and it still doesn't seem to work.
