The HUD elements are rendered to a set of prioritized 2D planes which then get projected into 3-space using an oblique (non-perspective) transformation. Different cards and drivers could be getting slightly different results for these calculations, causing some to lose pixel information.

FFXI doesn't render the 3D scene directly to the framebuffer. It renders it into a texture which is placed on a 2D plane "behind" the other HUD elements. If the resolution of this texture is different than the screen resolution it gets resized to fit. The only HUD elements that are actually a part of the 3D scene are the character/monster names and the linkpearl icon. All other UI elements are rendered separately.
