Scrolling with the user font

[ogul]

Scrolling works with the internal font.

But I couldn't scroll with the user font.
I also write fixed text in the user font.
Where am I making a mistake in scrolling with the user font?
Can you help me?

I couldn't scroll with the user font.

I see scrolling in the video. Isn't it what you expecting? Please be a more specific describing the problem

There is no scrolling in the following lines
dma_display->setFont(&FreeMono9pt7b);dma_display->setTextSize(1);
scrollText(text2, 128, 30, 5, 3); // X = 128, Y = 20, scrolling = 5, count=3

Let me continue working. I am sure I will find my mistake.
