Graphical issue / white vertival lines 
All in general my game works great. But since i started the game, I have this strange issue (video linked below). My detailed specs are attached as DxDiag.txt file.
I have some vertival flickering lines, appearing every some seconds no matter what place or area, that go mostly from the sky to the ground, sometimes just half way up. Bright lines, mostly white, sometimes there is some black in between.
First it seemed to happen only outside and when inside the houses, I was able to see the flickering lines through the houses windows. But in Velen I first recognised them also inside the houses (Blood Barons Fortress, etc.).
I tried every patch version. It doesn't matter, what graph. settings I apply.
AND the flickering also appears, while the game is paused (meaning while in the Main Menu).
Maybe it has something to do with the GTX 700 series issues i read a lot about, but i haven't read anyone else having this problem (which made me wonder what settings of mine could cause this, if it has nothing to do with the game or graphic card issues in general).
If anyone knows, how to fix it, i would be really really thankful, because it's the only issue I have with TW3 (luckily compared to all the bad things I read here).
Sorry for bad quality, had no other opportunity to record but my rather old mobile ^^
