I set myself up using DX11 (been using 12 since i build this machine a couple months ago). After 100 casts I never saw another glitch in the bobber at ultra settings. I did the winter's vale dailies and a few quests and still haven't seen any issues, so I'm going to call it fixed until it makes a liar out of me, thanks Ugh - this is why I post here, cause somebody (usually you or Mirai) will think of something I haven't.
