I’ve never had this issue before, but now when I launch Halo MCC through steam, there is no window. I hear all sounds and can hear that if I touch keyboard keys, UI is being interfaced with.
When I alt+tab I see Halo Master Cheif collection but there’s no window contents draw to the alt+tab menu. It’s like the window is just not there. I normally run in full screen. Is there some way to force windowed mode at least? Alt+enter didn’t work. Maybe I can mess with some settings and fix it. At least if I could run windowed borderless mode. Maybe some command line params?
