TFT mirrored text

I have a problem with tft shield 2,8 for Arduino. It is HX8357G (7575) and i use Adafruit_TFTLCD.h and Adafruit_GFX.h libraries. Problem is that text from sketch is mirrored. With setRotation() i can only rotate text but how to set it right, to not be mirrored?

Second question is how to clear buffer from tft? With some code or there is another way?
