I just started playing a little while ago and have really been enjoying it so far. However, there is a problem while playing that is starting to bug me.

On my screen no matter which mode I'm in (i.e. full screen, windowed) and if v-sync & triple buffering are hard turned on, I still have horitonzal lines coming on from the side of my monitor. This only happens while playing FFXIV and it doesn't really block vision on playing it's just there on the sides and it's starting to annoy me.

Any suggestions on how to fix this?
