If the hue bulbs are connected to the hue bridge, then unfortunately there’s no way at The present time to avoid a popcorn effect through the official SmartThings integration. Discussion in the following thread:
What you can do is use IFTTT to activate a hue scene. Using that route, the Hue bridge will groupcast the instruction to all the lights in the scene, which usually remove the popcorn effect. However, there may be some slight additional lag added at the front end because of the IFTTT piece. So that will work for some use cases but not others.
At the present time there’s no way to activate a Hue scene directly from SmartThings, although @ady624 Has said it may be introduced in future versions of webcore.
