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?
Wow, that was fast. Thanks.
My version is latest 4.4.2, is stock ROM for Telcel, Mexico. I'm using stock and tried with Apex, same thing. I tried with a custom wallpaper (a pic I downloaded) and I got the black bar, I used a wallpaper from my apex theme and the bar is back to transparent. Is there a way to have my custom wallpaper with transparent bar?
