If lightning strike occurs, semi-transparent blocks(glass, ice) and some mobs/entities behind the strike are rendered invisible.
Steps to reproduce:
1. Set the command inside a repeater command block (easier to see instead of waiting for lightning) to /summon lightning_bolt
2. Place some semi-transparent blocks and/or entities behind it
3. Watch in front of the lightning
Lightning causes semi-transparent blocks or entities to be invisible, you can see behind the blocks
The blocks/entity should still be visible or completly obstructed by the lightning
Note: The images show the blocks normally and then behind the lightning
