Areas in shadow, even adjacent to light sources take considerable time to light.
Only the blocks that light sources are in will illuminate, surrounding blocks remain in night/shadow for sometime after game start.

I have occasionally noticed something like this. In my case. it resolves within a second or two and happens sometimes when a new chunk loads (or reloads?), not just immediately after game start. It's as if the game were recalculating the lighting each time it loads a chunk.
That might or might not be the same issue you're reporting, or it may be the same but have a more problematical effect on your computer than on mine. Have you ever noticed it happening when you travel somewhere new, or where you haven't been for a good while?
Yes, It happens from time to time as new areas in the distance are generated. It also happens under trees and other places where there are shadows. On my computer it may last a minute or so. Makes it hard to get started. I have noticed that when it happens indoors, lighting or removing a torch will light the rest of the area immediately.
It sounds like the same issue I have noticed. You notice it most in shadowy areas because that's where the change is most drastic, but my hunch is that lighting updates are occurring, often invisibly, everywhere. I'll try to find out more details about the conditions that it happens under.
Thank you for your report!
