Re: Mouse cursor in CAS is acting up

@MoMooush  This issue is often caused by Reshade.  Uninstall it and see whether it helps.

If it doesn't, or you don't have Reshade, try disabling Origin in-game, both on the global and game-specific levels.  For the global setting, hover over your username in Origin, then click Application Settings, then More > Origin in-game.  For the game setting, right-click on TS4's icon in your game library, select Game Properties, and uncheck the box for Origin in-game.
