Something is going on with the trackview & X3b. I 1st noticed a severe graphical stuttering/pause issue while using Duende plugs. I figured that was just a plugin related issue, but after this morning of heavy editing I've noticed the trackview in general is "laggy" in comparison to X2. Just Zooming in/out with key commands & watching the play curser move down the line shows visible hesitation. This is only with the trackview, all other "panes" dock, inspector, etc are very responsive. Some type of overlay code issue maybe? Same session is snappy loaded into X2.
Any GPU changes made to X3? I'm using a Nivdia card on this system. 

I'm having the same issues. I also get...a line from the mouse. The time line moves, but sometimes a dotted line remains where the mouse was. Clips will stutter when dragging.

Hrmm.  Can you send us a project possibly?  PM me if I'm offline.  I would like to see how one of your projects loads up in X2 vs X3 on our end.

I'm having similar stutters on the video side.. but the audio doesn't glitch or pause... just the video lags. Just on X3b, same project (and all my previous projects in X2 were perfect).
