Autocad 2011 Paperspace Viewports Display Problems

[Dudemanbubba]

I have been running Parallels for some time now and have upgraded with each new version. I had upgraded to 9 and within a week my Windows virtual machine got corrupted and would not boot. Unfortunately, I had never made a snapshot... Regardless, I reinstalled Windows 7 64bit and reinstalled Autocad 2011.

Since I have reinstalled everything, Autocad is behaving oddly and I haven't been able to get any answers from Autodesk. I am reaching out here to see if this may be a Parallels video driver issue. Although, this was not happening on Parallels 9 prior to my reinstallation of the Windows virtual machine...

When I view drawings from paperspace that have viewports created, the drawing information that extends beyond the viewports in modelspace is ghosting on the display making it impossible to work on my sheets.

This is an image of what I am talking about:


The jumble of ghosted display items are not "really" there as when you print it doesn't show up. Here is a print preview:


The jumble also changes as you zoom and move around the drawing. Here are two images showing some of the ghosted items disappearing when I zoom in:


Any help is appreciated.

For anyone interested, I believe this has something to do with Parallels 9 video driver in the Windows. When I turn off hardware acceleration in Autocad, the display issue goes away.

I am hesitant to mark this thread as solved... I went the overly expensive route and upgrade my mac and got a new macbook pro 15 with retina display. The ghosting issue has gone away on the new computer running parallels 9... However, I still have my macbook late 2011 which is still experiencing the problem... It most certainly has to do with the pass thru parallels driver and the mac driver. If anyone still has the problem (and I can't believe it was me alone) good luck!

I am also having the same issue running AutoCAD 2014 on parallels 9. The problem occurs on an older, mid 2011, iMac. However, when I migrate to a newer, 2013 model iMac, the problem goes away. I am also having the same issue in Revit for 3D viewports only. As mentioned above, turning off hardware acceleration fixes the problem in both programs, but also slows everything down. Is there any other settings that can be changed or an updated driver available?
