Sluggish touch performance in EGUI 3.0?

Has anyone else noticed poor touch performance with EGUI 3.0 and MQX 4.1?  We have now tried this on both the Vybrid with CRtouch and on a Kinetis design using the internal A/D resistive touch control code.  In both cases the response to touch is slow and sometimes it misses an event.  I have verified with a scope that the CRtouch is responding immediately to touch events, but the buttons on the D4D screens don't react.  I have FASTTOUCH included in the flags for the buttons.

 

Thanks,
