Oh sorry if I misunderstood your question
I prefer dalvik with xposed. Because ART for now as they say is "experimental". From what I read, it's like a hit or miss thing. Some apps load faster with ART, some load slower than dalvik. And If you are using xposed modules, you're stock with dalvik anyway.
With the Xperience kernel, I have no idea. Because I am using fauxclock. And never encounter that issue with tricksterMod last time I used it. You can maybe try to do uninstall/install, clear cache and dalvik, reflash kernel. I'm no expert, so hopefully someone can help you futher.
