Thanks Sir Les....there's certainly a lot to try here, I appreciate your time .

But I think the answer could possibly be a simple thing. The other night I noticed that starting a brand new project the issues seemed to absent ...but I didn't spend long on it. But when loading an older project the issues were back.
So I am now wondering if the problem is due to opening up an old project originally done in Sonar 7 in X1D ? Maybe I didn't tick enough associated files during loading X1 or possibly something like that ?

I haven't had enough time to check, I may be wrong but I did notice this the other night ..I will be checking later tonight so I will repost ...

could be,...old projects might be assigned as you say to other attributes not found..and so, things go south in trying to use old in new software rendered upgrades...
 
what you can do to try to solve for, if so...is find the audio folders and ""import the audio only"", and start fresh in the new software.
 
Just to give that a go...Test it.
 
But tweaking for me, has helped me solve many issues with sonar..and other DAWS in the ways stated to get some of the little bugs out of the mix...LOL...and throughout...my posts is sound solutions for troubles..
 
Thunderbolt rocks!
 
Best wishes.

Is the audio playback solid? Is it just the visual/UI that jerks and stutters?
 
Are you absolutely sure you're not in CPU Conservation mode ?  (Pause/Break key)

you should consider seperate graphics card  , it's not that because sonar is 2D only gui that you don't need one ,
onboard graphics chipsets still use quite some cpu overhead so probably it's that interrupt that causes your discribed
screen behaviour

Yep, potpourri...a video card with 1gb or more is best to help sort memory issues with on board memory calls.
 
I think I posted that hint, in my last post...
 
So, Making a great system for things like audio, must be taken to heart.
 
Laptops might do for tracking a session?...(( I hate em my self ))...but a good solid build for this audio / video editing based desktop WS with plugins and such.... In a desktop body beast of a machine with lots of memory, good graphics card with 2gb on it,  and four cores or more if possible ( i Like the I7 intel myself), over head of 16 gb in the MB slots or better, is best to bring a well to do, and most capable system for...such tasks....the z97 boards are very good.
The x99?...too expensive...but more cores than 4 is something I am now playing with.
 
But some need portable machines...and laptops are popular with students.
 
Perhaps this is the cause of alot of issues with graphic glitching with laptops or video cards not having enough memory to suit the on board graphics and system functions ...memory allocation or refreshes?....and irq usage.
 
Seems something to do with it.
 
So , reduce the systems needs of irq usage might free up some of the bottlenecking or memory/cpu calls, and interupts.
 
Hope all this helps all ...
 
Cheers!

Hi,
have only had time to skim through this post but does your project contain tempo changes?
I have timeline stuttering if my project has a lot of tempo changes in it - for instance, I have extracted grooves from audio and there are many micro tempo changes.  Apparently it can be fixed by enabling AudioSnap or something on your audio tracks.
I just live with it on the projects where I've inserted many tempo changes.
