The Red/Black/White e-paper is only visible while refreshing #52

I have everything connected. When the controller refreshes the screen, I see a white background with the black text briefly, and then the display goes dark. The information is written on the screen, but it's like there is a nearly opaque darkish-red color on the screen. I've tried to include some pictures.

Any ideas on what might be going on?

White refresh: white-refresh

Red-ish-dark-ish opaqueness: nearly_opaque

Never mind. You already covered this. I had to uncomment DISP_3C_B in config.h, of course.

However, it does seem to flash quite a bit, as if it's refreshing several times per second before it stabilizes. Not sure if that's expected or not

Glad you were able to get it figured out. And yes that is the expected behavior. The waveshare color papers require quite a bit of 'flashing' to refresh.
