Rapid Fire Redstone Connecting to Pistons Creates a Graphical Glitch

When you use rapid fire redstone, pistons will glitch. (see screenshot) How to make:
1. Make a really fast circuit like this then destroy the torch really quickly.
rp:repeater r:redstone rt: redstone torch
r rp rp r rt
r rp rp r
2. If power is circulating you did it right.
3. Attach both sides of redstone to piston.
Tada.
