My son is running the game Fifa 22 on a MacPro under Windows 10, Parallels 17 and OSX Catalina. All was well until something changed yesterday. Now, no matter what settings we try, clicking anywhere the game's window causes it to collapses to c. 1/3 size, with the origin towards (but not at) the top left of the Mac's screen. Previously, it was stable at near full width, and with the menu bar showing at the top. Running full-screen works, but there isn't quite enough resolution for the game to be sharp. If we drag out the bottom RH corner to enlarge the window, as soon as you click within the game's window, it shrinks again to its former size. I have no idea what has changed to force the game to keep reducing to this smaller size. Any suggestions would be greatly appreciated.
