Using custom Glass pack for visibility and colour.
Steps to reproduce:
1. Place Stained Glass Block, Stained Glass Pane, etc.
2. Set Particles to Minimal.
Note: Setting Particles to Minimal is not required; a no-particle environment will work just as well.
Try placing a Torch (or other particle-producing block) near glass panes; note change.
