Display Error in Track Window When Moving Multiple Clips?

Is anyone experiencing this? I seem to recall this being a problem for me in X2a as well. It is quite odd.
 
If multiple clips (MIDI or audio) are selected in the track window, and said clips are located above and/or below the track-window's display area (see NOTE), then when they are clicked and moved, or moved+copied while in the lower portion of the track window's display area, then the clip images all shift down one track space.  If the bottom-most track contains a clip to be moved/copied, then it shifts down into the dark gray space which there is nothing.  However, upon releasing the CTRL or CTRL+SHIFT key combos, the tracks move/copy into the correct places, i.e. there is no resultant error in the placement of the clips.
 
NOTE: By display area, I mean the division of the track window by its vertical scroll bar.
 
From what I can tell, if the highlighted clips are clicked and moved in the upper portion of the track window's display area, then there is no display error.
 
I'll see if I can capture a good screenshot that illustrates what's happening.
 
For those of you who do test this, please let me know how it goes, and let me know what kind of video card you have. This had better not be yet another nVidia problem!
