bad display for high number

### Checklist

- [X] For Python issues, I have tested with the [latest development wheel](http://www.open3d.org/docs/latest/getting_started.html#development-version-pip).
- [X] I have checked the [release documentation](http://www.open3d.org/docs/release/) and the [latest documentation](http://www.open3d.org/docs/latest/) (for `master` branch).

### Describe the issue

It seems that when the pointcloud has high number, the display is "jumpy".

### Steps to reproduce the bug

```python
import numpy as np
import open3d as o3d

xyz = np.array([[7.63565630e+05, 6.29661919e+06, 2.80860000e+02],
[7.63565980e+05, 6.29661901e+06, 2.80820000e+02]])
pcd = o3d.geometry.PointCloud()
pcd.points = o3d.utility.Vector3dVector(xyz)

o3d.visualization.draw_geometries([pcd])

#then rotate the display inside the display window, it is not smooth
#when points are replaced by smaller numbers, it works just fine
```
