grey lines flick white when working in a large dwg / cutting & pasting as block.

Hi, anyone else have this problem?


when I am working on a large drawing and/or pasting as a block, all the grey lines (colour 8) turn to white. When I select a grey line, it flicks back to grey, but de-select, and it's white again.


If I toggle on hardware acceleration, the problem is fixed for a short while, and also if I turn it off, it is fixed for a short while, and also if I save, close and re-open it's good untill I paste a block....


I suspect it may be because of my setup and an un tested graphics card:


Windows 7 64 bit Ultimate - running through bootcamp on a macbook pro

Autocad 2012 Lt


Machine Configuration
Processor Speed : 2.2 GHz
RAM : 8103 MB

3D Device
Name : AMD Radeon HD 6750M
Manufacturer : AMD
Chip set : Radeon HD 6750M
Memory : 707 MB
Driver : 8.17.0010.1063

Your machine contains a 3D Device that is not certified.


Any Ideas? See attachment image


Also, there are two other computers in the office with identical setups, and I've never heard them complaning about this issue...

Is it just the way I do things?!

There are issues with Windows, vid card drivers, and MAC laptop hardware: toggling hardware acceleration is forcing your vid card to react when it normally does not. AFAIK there is no fix, your 'large' file is puching your hardware too hard.


If you haven't done it yet, see if there are updated (or sometimes downgraded) drivers for your vid card: also consider knocking down it's settings in Windows, for example from full 32bit color down to 16 bit or lower, turn off WIn7's Aero theme and other things to lighten the load on it.
