it's strange i don't have that problems..
i'm on stock 4.4.2 odex + gravitybox
it seems like Your ic_sysbar_back button got resized ..
i'm going to release new ones... we will get it working
edit2 : found the problem! i'm using navbar custom settings from gravitybox so I tried to disable it and now I have the same problem
will post new keys soon, don't worry
