I been having the same problem on the last few Hyperdrive Rom builds.
1. When Trying to change the wallpaper for "Home and lock screens" I always get "Unfortunately, Setting has stopped"when selecting the wallpapers option.
2. When trying to reload the status bar from Hyperdrive tweaks it always freezes and says " Unfortunately, the process com.android.systemui has stopped" and i'm forced to do a batter pull.
3.My clock never seems to change color in the status bar, even when I installed Xposer. Not sure if i'm doing somthing wrong or what.
