Problem with text display - Font is cropped in full-screen mode

I am currently building a reading task that runs online.
So far, it is running well, but the bottom of some characters (g and y) are slightly(!) cropped. I am using Arial, 0.1 letter heigh, and 0,0 position (see screenshot). When I exit full-screen mode, the letters are no longer cropped.

As suggested in various posts, I have changed the font, size, and spatial units, but the letters are still not fully displayed.

Try adding a \n newline character at the beginning and end of your text.
