Better Box Out/Spotlight Transition?

I really like the box out transition, but as the transition occurs the scene becomes all pixel/jagged.  (same with spotlight)  I saw people were posting about this like a year ago but nothing came about.   Is there any updates on the issue or is there a way to re-create the box out trans?

Thanks.

I'm not aware of any changes to the existing transitions. There is a transitions extension you could use to create a new transition or recreate an existing one with custom adjustments: http://community.stencyl.com/index.php/topic,50434.0.html

Looks interesting, but I'm getting an engine extension error.  Doesn't seem to work with Stencyl 4 

What is the error?
