Forum:Contents of chests & inventory are dark

Everything looked normal last night. This morning, when I open my inventory or a chest, the contents are really dark and hard to see until I pick one up. Then it looks normal, until I re-place it in the inventory or chest, and it goes back to looking very dark. I'm having the same problem viewing crafting tables and furnaces, etc. I've tried adjusting the brightness settings, but that doesn't help.

Any ideas?

Thanks!
