AutoCAD point cloud issue with live section objects

Hi there,

 

I have been using recap imported point clouds to generate drawings for the past couple of years and have recently come accross a few issues which is starting to frustrate the workflow so here I am hoping someone can help.

 

Scenario:

 

I import a point cloud, create square ucs to the object, create live slice section through the point cloud and start to draw.

 

When I zoom in and out i can see the point cloud getting distorted see attached pics 1 & 3 at different zoom (please note the polyline hasn't moved).

 

the polylines get distorted from time to time also where i see the grips are far away from the vertex see pic 4

 

So far I have narrowed it down to the visual styles.

 

2D wireframe - fixes the polyline distortion but not usefull as point cloud isn't visible

3D wireframe - gives me the above 2 problem

All other visual styles except Hidden- does the above + additional problem below

Hidden - fixes the above 2 but behaves below.

 

In the Hidden visual style the above 2 problem goes away however it creates a selection issue where the section object always gets selected and all drawn elements are not selectable unless I select all which won't help with the modifying side of things.

 

If anyone can advise I'd be most grateful

 

FYI - I'm using Autocad 2017.1.2, graphics card driver is up to date etc. Tried different hardware acceleration settings to no luck.
