Same problem for me. I only get the blue tint when I have ALM turned on BEFORE loading the viewer, otherwise everything is fine.
I can open graphics during the blue login screen with ctrl+p and go to Graphics tab, turn Advanced Lighting Model off. Press OK. Close viewer entirely. Re-run it and all's fine.
I can even turn ALM on in-game with no ill effect, I just can't START the viewer with it on.
