@Architector_4 given that the proposed fix (reversion) now breaks my system, can I ask if you could possibly try the following code in Processing 3.4 on your system and see if it works? The lack of bc profiles in your first error message is intriguing me.

```auto
void settings() {
  System.setProperty("jogl.disable.openglcore", "true");
  size(100, 100, P3D);
}

void setup() {
  PGraphicsOpenGL pg = (PGraphicsOpenGL)g;
  println(PGraphicsOpenGL.OPENGL_VENDOR);
  println(PGraphicsOpenGL.OPENGL_RENDERER);
  println(PGraphicsOpenGL.OPENGL_VERSION);
  println(PGraphicsOpenGL.GLSL_VERSION);
}

void draw() {
  ellipse(width/2,height/2,width,height);
}

```
