Minor, but annoying: temporary lock up with Seraphim

[TSFF19 0]

Ok, for the past few days or so, ever since shortly after I entered Artamak with my Seraphim, everytime I try to load her up the screen suddenly freezes and starts making these weird black flickering lines horizontally across the screen. Now, I've found that I can bypass this by using ctrl-alt-del while its stuttering and re-opening the game, but the weird thing is, this only happens when I load my Seraphim. It doesn't happen when I load any other characters.

 

So...yeah, nothing major, just annoying. Has this ever happened to anyone else, and can it be fixed?
