We have a rolling subscription in the office and one of the guys wanted to be the “guinea pig” for the new version of AutoCAD LT, 2014.
Install went OK but the status bar at the bottom of the screen kept flickering, with “unrecognised” coming and going.
We already had the certified driver installed and tired turning off hardware acceleration to no avail.
However so far this seems to have been solved with upgrading to the latest driver for the ATI Firepro V4900.
Hope this helps someone.
