white wire with red dashes on the new switch
Sounds like that's for a dual switch setup.
The question is, is this dangerous, and/or should I do anything about it?
Not necessarily dangerous, just less safe.
Me, I'd pull the source cable (Romex?) & see if it has a ground. If so,
I would put it to use. In addition to the safety factor, a grounded dimmer
switch is less likely to cause any RFI issues.
I'm hesitant to open this thing back up again -- I had a devil of a time getting the switches to line up and come enough forward for the faceplate, it seemed that the plastic box was too far back into the wall and not lined up well with the hole in the wall. I'd probably have to go digging into the wall to find the source cable you're talking about.
