[Q] camera not working properly after root, pic attached topic

This is what the camera looks like. taking up less space than usual. also none of the camera buttons / options work, i can only take photos with volume keys. cant change to front camera or adjust any settings
(Camers isnt using whole screen, the entire thing takes up only the top right corner.

Lastly, the bottom left touch button to flick between open apps/ programs isnt working either, and keyboard occasionally freezes.
And idea how to fix?

I rooted and using XPOSED.
