Sorry for my english, I'm from Mexico.
Your English seems better than most of the native English speakers I see post here, so no worries.
As far as your question, switching back to Dalvik won't hurt any of your apps, but it may take several minutes for your phone to boot up the first time after switching back.
I'm not sure ART would affect the nav bar transparency though. What version of Android are you running? Is it a stock or custom ROM? Are you using the stock launcher? Did you apply a custom wallpaper?
