Exactly, on my system, they do not freeze if I display them individually. My biggest issue now is the synth cutting in and out. I am use to work around's; however, the synth plugins cutting in and out makes them completely unusable.  

regarding the blank ui, what are the published open-gl requirements? i.e., what minimum version of open-gl is required?

Can anyone reproduce this with just a single audio track playing back, and with LP EQ and LP MB on the master bus?   I cannot after repeatedly toggling the two back and forth during playback (Windows 7).    Here's my OpenGL info, as outdated as it may be:
