My office recently received the update from 2013LT to 2014 LT, and after installing them, I'm noticing an issue that I don't understand.
If you go to the link below, you'll see a video of the problem. Basically, when more than one drawing is open, as the user pans around or zooms in and out, the application status bar starts to go nuts, with the word "unrecognized" popping in and out, as well as a small symbol to its left. Also, while all of this is happening, the colour in the layers bar at the top of the drawing flickers somewhat randomly. So far, 5 of the 11 copies have had this issue, and 3 of those licenses haven't been used yet.
I'm experiencing this on multiple machines, across multiple platforms. This includes Core I7's with 8 Gigs of DDR3 RAM and Radeon 6450's running windows 7, all the way to Core 2 Duo's running 64 bit XP with 4 gigs of DDR2 RAM.
Please see video below:
Any help is greatly appreciated!

Change your hardware settings in LT2014, see if that helps.
Also, Autodesk Supported Graphics Cards List and drivers may have a driver you can use:

Hello from France
If no problem of the same PC with ACAD LT 2013 (+ SP 1.1 - I believe),
I suspect something related to the graphics card and its driver !
If I understand well : you have the probleme on Win XP Pro SP2 64 bits
AND on Win Seven Pro SP1 64 bits ??
*** 1 *** So please test the ACAD LT 2014 with Hardware graphics accelerator DISABLED !
If no problem : it could be the driver of the graphic card ...
If yet problem :
*** 2 *** Change the settings of your graphics driver : disable the 16 Millions color Mode (24/32 bits)
Reduce it to 15/16 bits color mode (32000/65000 colors)
If no problem : it could be the driver of the graphic card ...
If yet problem :
Could be some Windows Update or other Software installed ...
Good Luck, Bye, Pat

Okay, so I've tried turning on and off the hardware acceleration, which has no effect, except for making things slower when off and quicker when on.
I tried installing the latest graphics drivers, but to no avail.
All our computers auto update with the latest Windows updates, so that shouldn't be an issue. I've only checked to make sure on a couple that are affected, but it looks like all should be in order on this front. I don't think hardware is the issue here, as the hardware having this issue is quite varied.
This post below is very similar to what I'm getting as well. That "unrecognized" thing keeps on flickering in and out and it's incredibly annoying for everyone using it. What is "unrecognized", and how do I get rid of it?

Thanks for all the help, so far, though! Hopefully we can get this solved so everyone can stop bugging me. 😃
Hello
Have you tried this (if it's possible) >>>
*** 2 *** Change the settings of your graphics driver : disable the 16 Millions color Mode (24/32 bits)
Reduce it to 15/16 bits color mode (32000/65000 colors)
If no problem : it could be the driver of the graphic card <<<

The drawing size may have little effect on whether or not it works when one is open and the other is not.
Depending on your System and Video Card, 6 MB of RAM is on the low end. Double or more would be desirable.
You may be seeing a limitation in your computer specs.
Provide some more information on your setup.

We have the same issue, we test ran one user on the new AutoCAD LT 2014 and he is experiencing the flickering "unrecongnised" icon also.
We are running Windows 7 64bit, have a certified card (for 2013 as 2014 certification is not there yet), running the certified driver. Turning hardware acceleration off (or on) does not help, this flicekring happens when zooming, panning and changing between model and paper space tabs.
There is a pause while this flcikering occurs as it it is trying to load something or do something fails (or possibly suceeds) and then carries on with the chaning of tabs or the zoom. It is in the same location as the scale so is there some dynamic scale changing feature of 2014 that might be culprit (clutching straws I know). We are going to try to the latest driver from ATI (not certified by AutoDesk) to see if that helps.
So our 2014 rollout is halted until this can be resolved as it is quite annoying!
We upgraded to the latest ATI driver and this appears to have sorted the issue! Will keep you posted if it returns....
NVIDIA Quadro 600, as noted, 2013 is only available as you are ahead of Autodesk with 2014:
Hello
I was almost sure it was a problem with the graphic card driver !

There are no certified vid cards for LT2014 yet as of this date. Past performances and drivers are no indication for future smooth compatibility.
Autodesk needs to identify it as a problem, then post a fix for it: so far there is no record of such a posting or fix. It may happen soon, but no one around here knows unless someone from Autodesk jumps in with an answer.
You'll have to wait for fixes to appear for LT2014 on the website in the meantime:

Hello
Just a stupid idea :
Can you test completely disconnected from Intranet / Internet Network ?
With DWGs stored locally ...
If yet problem : with Anti-virus disabled completely ...
and maybe all unnecessary Windows Services stopped !
