setCursor not working properly. #10

With the Huzzah8266 and EPD Featherwing: calling the two functions one after another but the X position in setcursor is wrong in the first function (upper red text) and correct in the second (lower red text).

void display_dir(String s) { Serial.println(s); epd.setFont(&FreeMonoBold12pt7b); epd.setCursor(10, 0); epd.setTextColor(EPD_RED); epd.print(s);
} void display_swell(String s) { Serial.println(s); epd.setFont(&FreeMonoBold12pt7b); epd.setCursor(10, 90); epd.setTextColor(EPD_RED); epd.print(s); }

@tavdog hmm does it work with the built in font? this would be a bug in GFX not eink i think

I narrowed this down to a leading "\n" in the string. So if there is a new line the string it brings the cursor back to the edge of the screen I guess.
