This angular repository tries to reproduce a bug that I'm having when trying to discard fragments with different InstancedGeometryBuffers in a scene.

The problem is that when I discard them, they look like they are flickering, not disappearing completely but showing some pixels with the same colors as the scene's background color.

• First of all, the bug seems to appear only on dedicated GPUs (mainly NVIDIA)
• Click the second button in the top-left corner to add elements of the Figure2
• Click a couple of times the first button in the top-left corner to add elements of the Figure1
• Click the third button in the top-right corner to discard the Figure1 elements.

The Figure1 elements discard it's fragments and they don't appear

Some Figure1 elements flickers and you can see some pixels with the background color. You can only see these pixels when they overlap with a Figure2 element (that is not discarded).

• Top-Left

  • Add (figure1): Adds instances of the Figure1 Geometry
  • Add (figure2): Adds instances of the Figure2 Geometry

• Top-Right

  • Toggles the background color of the scene
  • Toggles the scene that is currently rendering (the actual scene or the hover scene)
  • Show / Hide element1 instances
  • Show / Hide element2 instances

• Bottom

  • Changes the Figure1 Geometry
  • Changes the Figure2 Geometry
