Is anyone else running into tons of issues with the Dell Thunderbolt docks and DDPE?

We're finding that if we use the latest AsMedia drivers DDPE will function, but the docks become completely unstable (i.e. extreme keyboard lag [pauses and multiple characters per keystroke], mouse drop outs, display flicker). If we roll the AsMedia drivers back to the to what ships in the OEM image the dock works, but DDPE stops functioning properly. 

Seems like one group at Dell isn't talking to the other and we're stuck in the middle.
