drawing duplicates itself on the screen

[Anonymous]

I have a problem with 2015.  It will suddenly replicate the line work in the drawing.  I can type regen and it goes away, but it comes right back unless I restart autocad MEP.  Has anyone else had this problem?  Anyone have a solution?  I have included a screen shot.

This looks like a graphics display driver issue.

Can you check to see if your graphics card driver is up to date and a Autodesk certified driver? Please go here and select Graphics Hardware, pick AutoCAD for the product and 201x for the release, select your operating system and graphics card manufacturer, select All and select Find.

Once the search is complete, look for your graphics card and select on that link to see if there is a certified driver for your card and if so, you can download the driver right from this site. If you have an older driver installed, please install the certified driver and then restart your computer and retest the software. If your card is not listed, then go to the manufacturer's website and download and install the latest driver available for your graphics card.

If that doesn't work, try turning OFF hardware acceleration. Type 3DCONFIG at the command line and toggle hardware acceleration off.

Thank you I will give this a try!

Our IT people say the driver is good, so we are trying the 3Dconfig toggle off hardware acceleration.  Hopefully that works, so far so good.  Thanks again for the reply.
