Crashing with rapid Shift + MouseClick

CW

Is there a bug I'm not finding documented wherein if while holding down the shift key and rapidly clicking within the map causes the client to crash with a white screen and with no error to give a hint towards the cause of it?

The clicking has to be rapid to reproduce. On the map I've got a FillSymbol that has a VisualStateManager but I cant find anything telling me that would be the issue, anyone have any advice or experience with this defect?

Hi thanks for the response. A whole solution to try against would take me some time to slap together since what it sits in now is gigantic, however here's an abridged version of the view. One of my guys wants to blame the FillSymbol, but I think something else is the culprit, but so far I haven't been able to retrieve any hint of the error to help me investigate. Let me know if anything jumps out at you, another pair of eyes is greatly appreciated!
