How can I position this line of text

[Aleph-Design]

This is the result I get:

When I try to lower the line, all I get is rubbish or working TFT-screen at all.
`void loop()
{
pTft->fillScreen(TFT_NAVY);
pTft->fillRect(0, 0, 320, 50, TFT_YELLOW); // 1. OK
pTft->fillRect(2, 2, 316, 46, TFT_RED);

pTft->setFreeFont(FSSB18);
pTft->setCursor(75, 15);
// Set text colour and background
pTft->setTextColor(TFT_YELLOW, TFT_RED);
pTft->println("- WEB RADIO");
}`
Any help will be appreciated.

Further experimentations learn that using a smaller font (FSSB12) all is well.
But, when using FSSB18 - which is what I want - the TFT- screen just keeps flikkering rapidly.
What does FSSB18 that FSSB12 does not?
