Display problem

When I'm using Xiaomi Redmi note 2 with android 5.0.2, display goes glitchy.
Background, as well as the floor and the ceiling, will move glitchy if the cam is targetted to a moving object.
Additionally,if in edit mode, the grid will move as the glitchy background do. But objects will snap to the grid properly.
Hardware:
CPU:MT6795M(Helio X10)
Display:PowerVR Rogue G6200
Software:
Android 5.0.2(rooted,xposed installed)
MIUI9
Principia:1.5.1

In android 4.4 and android 6.0(Both devices have qualcomm cpu),there's no problem.
Whether the problem is of the device or of the system?

Please save the level then test.
