Problem with textures (The Witcher 3: Wild Hunt)

Good night, I decided that to pass the 2 big dlc from the Witcher 3 after a long pause, not the game and met some texture bug. Previously went through the whole game and not seen it, the PC configuration has not changed to the word here it is:
Core i5-3470 3.2 mhz
Radeon R9 270
8 Gb Ram DDR3
Version 1.30 of the game from GOG

The game is all fine in terms of FPS, I play on high - the beyond 50 fps stable in Full HD. The only problem is those texture bugs, there are extra textures where they shouldn't be as the screen, sometimes there are transparent textures.

So now I tried to fix it and it did not help:
- In the settings of the graphics cards exhibited a level of tesselyatsii ranging from x4 to finish x16 and alternately run the game.
- Downloaded and installed new drivers
- Play with the graphics settings in the game ranging from the lowest and ending with the beyond, no change. The texture of the excess as was and remained.
- Tried to turn off video profile for this game in the settings of the graphics card.
- The temperature of the video card in the normal 45-55 degrees so for this reason not to write, and also it is not overclocked.

Like everything, nothing is forgotten. Saw that people have encountered on this forum with the same problem, their solutions were tried as described. Maybe someone knows what could be the matter?
