With a lot of custom fonts and large font sizes, characters disappear with P2D / P3D

With a lot of custom fonts and large font sizes, it can be that characters are not drawn.
Here i draw the text "HSLAB":

One of the weird things is, that if you disable noLoop() that it works again.

Font:
https://fonts.google.com/specimen/Source+Code+Pro

int font_size = 400;
PFont font;

void setup() {
  size(1200, 350, P2D);
  noLoop();
}

void draw() {
  background(0);
  
  if (font == null) {
    font = createFont("SourceCodePro-Black.ttf", font_size);
    textFont(font);
  }
  textSize(font_size);
  fill(255);
  text("HSLAB", 0, height*0.85);
}

No source file or test is named. Start by running the supplied Java sketch with P2D and P3D, using Source Code Pro, a large font size, many custom fonts, and noLoop(). Done means the HSLAB characters render consistently in both renderers without requiring noLoop() to be disabled.
