SetFont() always transparent background #135

Hello, if use some GFX font, then the background color for the text on the same position is transparent. pOLED->setTextColor(WHITE, BLACK); pOLED->setFont (&FreeSans12pt7b); pOLED->print ("12:35:56)"; next second writes over the "6" and do not clear black pixels. If I do not call SetFont(), it works even with bigger textSize.
