Reshade might bug the graphics in the Main menu. Having a key to disable the effects while in the main menus is advised. I use the "Home" key for that, can be configured in Reshade.ini with the line: KeyEffects=33,0,0,0
This will work with any CMx2 game. This means, all Combat Mission games using the new engine (CMSF2, CMBY, CMBS, CMCW...).
