Not sure what the issue is but the background in P3D does not seem to be refreshing. The screen is not cleared between frames. This has happened recently and happens on old sketches or just simple 3D examples. Running Window 10. Happens on a couple of computers but not others. Not sure if this is because of a conflict in a windows update,etc. Is anyone else experiencing something similar?

Reinstalling or updating video hardware driver might help.

Thanks, tried that. Also have tried it on a couple of PCs and the issue happens on most but not all of them. Cant figure out if it is an issue with a windows update or not. Not sure what is different between the PCs with/without t this issue.

Here is a link to a screen capture of what;s happening: [https://vimeo.com/352587524/3a17d79213](https://vimeo.com/352587524/3a17d79213)

The code is in the description of the video

if it persists on a specific computer try update graphic card driver?  
and check again.

some info might see by adding

```auto
void mysysinfo() {
  println( "System : " + System.getProperty("os.name") + " " + System.getProperty("os.version") + " " + System.getProperty("os.arch") );
  println( "JAVA : " + System.getProperty("java.home") + " rev: " +javaVersionName);
  //println( "\n" + isGL() + "\n" );
  println("OPENGL_VENDOR: " + PGraphicsOpenGL.OPENGL_VENDOR+" OPENGL_RENDERER: " + PGraphicsOpenGL.OPENGL_RENDERER+" OPENGL_VERSION: " + PGraphicsOpenGL.OPENGL_VERSION+" GLSL_VERSION: " + PGraphicsOpenGL.GLSL_VERSION);
  println( "user.home : " + System.getProperty("user.home") );
  println( "user.dir : " + System.getProperty("user.dir") );
  println( "sketchPath : " + sketchPath() );
  println( "dataPath : " + dataPath("") );
  println( "dataFile : " + dataFile("") );
}

void keyPressed() {
  if ( key == 'i' ) mysysinfo();
}

```
