Came across a weird bug happening in Mafia 3 whilst using Reshade 3. I setup multiple hotkeys and when I clicked one of them, the game would zoom in about 25% of the top-left section of my resolution. I don't remember setting any preset to do that.
What's more strange is that the zoom in on hotkey press would move around. Sometimes it would be on "-" then it would be on "*" then it actually moved to the "Shift+F2" hotkey to open the GUI! My resolution is 1920x1200 so I guess it was zooming into 1440x900 maybe...
Here's 2 screenshots of it happening:
