AutoCAD LT2015 line across the screen problem

[Anonymous]

A colleague of mine is having a problem where on fairly large drawings his laptops AutoCAD LT 2015 produces unclick able lines from a base point of 0,0,0 whenever he Zoom/Pans. These lines then disappear and a new set of line appear when he again Zoom/Pans. It also slows the programme down considerably and makes it almost un-workable. 

He mentioned that the problem seems to appear when the drawing has had a lot of copy and paste.

When i open the .dwg file on my full version of AutoCAD 2015 i have no problem at all.

Any help would be greatly appreciated

P.S i have attached a screen shot showing the problem.

I also get these unslectable lines !!!!!!!!!

But they can start anywhere and end anywhere !

A regen will remove them, but then others appear in another location!

I've actually have given up on using Autocad 2015 and gone back to 2014

Still way to many crashes, display issues !

Also my company is just about ready to stop the "Subscription Licenseing"

2015 has been out now since March, SP1 since June and still we can not reliably use 2015 !

I trully belive this all revolves around the new display foundation they've used for 2015.

We have maybe 50 seats scattered around the states........all Win 7 different HP computers different

video cards, and all of them have gone back to 2014 becuse of display issues !

It appears we may never see SP2 to address these problems !

I've used every Autocad versions from DOS 9 to 2015 installed them all set them all up, but I've never seen

so many problems with this release !  (I even had better results with Win-95 version 13 !!!)

My adice to users still have these issues.........contact your reseller and let them know how you feel !

Maybe THEY  can get some results from Autodesk !

I would be happy to get the hands of one of those files.

The files are NOT the problem !

 These can be very small files, simple 2D blocks only 160K file size.

  The Display "Engine" however they want to call it............change IS the problem.

The other display problem that occurs is while moving an object then placing it in the new location,

it disappears !  A  Regen or Pan brings it back !!!!!! very irriating !

Can you post one of those small files?
And a similar that's not have the problem?
Or is it in every file you open?
If I can not reproduce the error it would be nice with screen shoots of the garbage.
