Apologies for the somewhat cryptic subject. Couldn't figure out how to summarize this in 80 characters of less. 🙂
This problem has bugged me for several versions. I'm using 2012 at the moment as I haven't wanted to get into the fiasco of a new drawing version with 2013.
Anyway, the image below really tells the story for me:
You can see the behavior of the crosshairs overlapping a drawing line with Hardware Acceleration On and Off. It's always been handy to have the drawing lines or crosshair go to the "negative" color when they overlap. However, with Acceleration ON, that behavior goes away entirely. Why?
This happens on every machine we have. It's not isolated to one machine or video card. In fact, on this same machine I have had this happen with two entirely different video cards.
So, I have to choose...hardware acceleration or overlapping negative colored lines. Decisions, decisions.
Anyone have an answer to this or is it a persistent AutoCAD bug?
Thanks!

In this case the issue does look graphical and possible system based. We have seen a number of instances similar to this that are easily resolved by toggling this HA setting within the software to help lesson the load introduced on the graphics system. Not all configurations can fully support the HA setting turned on. For reference I have included the technical solution from our website below on cursor performance settings within the Windows 7 environment and out supported products (2010-2013 release).

For additional reference I have include a link below with an overview on Hardware Certifications and details on Hardware Acceleration.
