--- Comment #3 from Béla Gyebrószki gyebro69@gmail.com --- There is a workaround: disabling the opening movie in Alpha Centauri.ini so that the game loads the menu directly, makes the problem go away.
[Alpha Centauri] DisableOpeningMovie=1
I'm using: Xorg 21.1.8 Xfce 4.18 with Xfwm as the window manager
