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.
Exactly the same problem here.
10 seats of Autocad 2014lt, all graphics drivers up to date but when more than one drawing open get flickering and unreconised. Very annoying
The file patch or the registry patch seem to work nicely to solve this issue. For ease of installation I use the registry patch these days.
