Hi friends,

These are my least favourite posts, but again as I start Processing up after a bit of an hiatus, I seem to run straight into problems. Searched the forum but could not find any other reports… is no-one having issues using the P2D or P3D renderers after upgrading to Big Sur?

I can’t seem to draw anything but a white window when I switch from the main renderer:

```auto
void setup()
{
  size(1440, 700, P3D);
}

void draw()
{
  background(0);
  
  fill(255, 0, 0);
  rect(0, 0, width/2, height/2);
  // I see nothing but white
}

```

Found the report (and workaround) on github: [Big Sur seems to have broken P3D & P2D renderers · Issue #6121 · processing/processing · GitHub](https://github.com/processing/processing/issues/6121)
