I installed the local d3d9 dll with Metal Gear Rising Revengeance on Steam. After a few minutes in game, the steam Big Picture overlay menu options will become invisible and there’s about a 10% chance for taking a steam screenshot to cause a crash. I did mess with settings in the Special K control panel including disabling the separate screenshot path and disabling other APIs. These issues don’t happen if the game is just vanilla with no Special K. I don’t remember any of this being an issue with the old Big Picture design.
I have no idea what’s wrong with the Steam overlay, sorry.
The good news is that Special K can take screenshots for the Steam overlay if it’s broken. Enable the screenshot hook.
