When using the FX effects, a use case exists whereby you can blink and land on a no-show situation - I think this stems from the fact that the blink code just cycle between show/no-show where it should repeat through a complete "no-show and then show" for every N times.

The following code snippet will show the bug, but you have to be lucky (or unlucky) to see it... it does happen if you try hard !!
