I tested Hitman 2 and Lara Croft: Tomb Raider Legend with DM 2.6 and can confirm that enabling both features makes them hang into a black screen. Disabling either feature make the games work again.

This happens whether the new screenshot feature is enabled or not and did not happen with DM 2.4, which is the version I was using before. Some users report the same problem with 2.5.

Thanks.
