At install time, running the .sh file gave me these errors:

But the game installed fine afterwards. I currently run with 2 monitors using twinview, main monitor is the right one at 1680x1050 and secondary is to the left at 1280x1024. When I run the game, it loads on my primary monitor the left half black and the right half showing 3/4 of the game screen.

I can change the resolution in game but this doesn't help. Changing the resolution and fullscreen=true/false line in ~/PenumbraCollection/Overture/config/default_settings.cfg doesn't do anything.
