Had issue with V8 also. Church setup: 41 Chromaq inspire house lights. 6 adj led flat par. 4 led strip light 24 channel dmx deciders.
When I change scenes on live buttons I get a random quick flicker. Scene works and dims from/ to properly but has that quick noticeable flicker. Same button will work for me for long time or short time then will flicker. Makes all lights flicker. It has happened enough times that I must question it.
Has happened also on timeline when going from one scene to another. Would do it randomly but work great other times.
Does not cause an issue except makes me look like an idiot with the lights flicker off for split second.
New windows 10 HP 64bit. 2 terabytes. Touchscreen all in one. I5.
Thanks
