Display issues with motion loop background

Hi,I bought a Worship Extreme Pro license a few weeks ago, and i’m encountering some display issues.The problem is that whenever i use a motion loop background with lyrics on the foreground, i have a lot of white flashes and display is blinking very often.I tried to change the display and cables, but the problem is only with worship extreme using motion loop backgrounds (I don’t have the problem with image background or movies).I use a 2011 Macbook pro with core i5 and display is a projector 1080p connected with HDMI).Do you have any idea to solve this ?Thanks.

One thing you can try is lowering your output resolution. Try 720 instead of 1080. Because it's an older machine, you may see a boost in performance with the lower resolution.
