Possible Graphics Problems?

[Hurlstone]

Hiya everyone, please forgive me if this is an inappropriate issue for this topic.

So, I started playing the game around ten days ago now, absolutely loving it, but yesterday an odd thing started happening. Spells my character cast were constantly flickering, as did other effects, such as the stones orbiting my Titan Summon constantly flickering. I logged out of the game and then immediately back in, and everything was fine. Today everything has, once more, been normal, that was until a cut-scene played and a sudden shaft of green flickering light interrupted the scene for a few seconds. After the cut-scene ended, my spells and stuff went back to becoming all flickery as they were yesterday. Once again, I logged out and when I went back in everything was fine and dandy.

Could this be a game problem, or a sign that something is wrong with my graphics card? I play on a laptop, and my graphics card thingy is a GeForce GTX 660m. It is up to date, not including a beta drive that is available. It was a very hot day...

Any help or advice would be extremely appreciated, thanks in advance!
