Tried everything including driver updates, clean installs and graphic settings. The bug looks like it is shader related. Bug is still in the latest game update.
Read another post about changing shaders, its good and working once on low.
Graphics are my current issue, before the Apr 1st update everything was fine, now the game made me think my GFX card had crashed. have tried clean re-installs of the game and also updated drivers to no avail.
