I'm using right now Xiaomi.eu rom, and it happens to me too, using a theme from China store.
No matter if I reboot, sometimes menu is like that (not all times) but is some kind of annoying...
All I have to do to get this work is killing the settings app and try again.
I tried to remove all gapps from latest stable firmware but it ends in bootloop (/system/app & /system/priv-app)
Does anyone know how to remove ALL gapps (Google Play and Services also) safely?
For the record: I was using chinese rom, gapps free but it has notification errors.
