2014 Unresponsive in X-Ray mode

[kupono]

SU Pro 2014 v.14.0.4900
Win8, NVidia GT 750M, driver version 335.23
OpenGL #63, hardware acceleration on, fast feedback on, max texture size off

SU becomes unresponsive when shifting to x ray mode in a moderate size model while in hidden line style-mode. Haven't checked other modes. I had to use task manager to kill SU about 4-times so far. If I open the component and hide all else, then go to x ray mode it seems to work okay.
