X2 Playback Meters - Question and Possible Bug

Has anybody else had issues with X2's playback meters hanging and not resetting themselves on reset?
I have just been playing with X2 (and really liking it so far).
I have  3 or 4 simple instrument tracks all set up to "input echo" from the same MIDI input - live keyboard.
Does not seem to be exclusive to the instrument, but inevitably a big pad in Rapture and/or Alchemy causes the meter to simply freeze for that track. The CPU meter is nowhere near 100% loading so I don't think it's a CPU issue.
This has occurred 3 or 4 times now, and currently I was playing around with AAS' String Studio, Rapture, and Alchemy with Kontakt, all playing simultaneously. Both the Rapture and Alchemy meters froze, and a "Reset MIDI and Audio" fails to reset them. 
(It looks like I am able to reset the meters if I scroll down the track view, then back up again).
I carried over all my settings from X1D expanded and it looks like the meters are otherwise behaving normally.
Not a deal breaker by any means, especially if scrolling down the track view resets things consistently, but unusual behavior nonetheless.
Just wondering if anyone else has seen something similar, and if so, maybe the can also fill in the gaps on when/where/why/how this occurs.

thanks

Just a soliloquy  at the moment. Hopefully Bill or someone from Cakewalk can take a closer look at this to confirm - 
Actually a really simple recipe to reproduce - (Not tied at all to multiple tracks per my first post)- 

I have about 30 tracks in my track pane, and another 9 busses in my bus pane.
1 instance of any soft synth (I am using Rapture), input echo enabled, playing live from a MIDI controller.
The playback meter freezes as I scroll up and down with the mouse wheel in the track pane, where the track I am playing is on or off screen - 

The inspector and the console meters behave normally.
Behavior is the same for either simple instrument track or separate tracks after splitting.

if nobody can reproduce this, maybe it's a graphic card issue on my system(?) Have not seen this behavior prior to X2.
