You reinstalled the OS and made some significant changes as well (Xposed and what else?). The MotoG is a "completely" different device, it runs an almost stock Android OS.
Have you changed the build.prop? Apps not fitting on the screen can be caused by the build.prop containing an ID, that suggests a different screen res. / ratio / density, etc.
I would suggest reverting the changes (one by one and reboot between) you made with Xposed modules until it changes back to a stable state.
(You didn't give much information about your system or which apps you already installed, so I can only speculate what causes the errors)
