--- Comment #3 from Ronny Schmatzler schmatzler@googlemail.com --- I guess you should try out the MESA drivers, it really looks like an Nvidia problem to me.
I compiled the latest MESA drivers yesterday (20140620) and ran Hard Reset, no problems with any shadows:

P.S.: I can't test with fglrx, can't get it to work for 32bit applications. The closed source drivers from AMD are horrible.
