I have for a long time had trouble with flickering mouse in game 0AD. No other app or software have this. I have tried all thinkable troubleshooting in Win 11. Im kind of lost. It makes it very hard to play when mouse pointer flicker between arrow and hourglass frantically all the time in the game. In lobby its fine. No joystick or other HID connected to PC. Just mouse and keyboard. Please help me out here.....
Is it a system hourglass cursor or in-game one? Do you have any mod installed? Could you record a short video?
Another way to possibly solve it is to change the type of the cursor. For that you need to add the following line cursorbackend = "system" to your user.cfg (you can find a path to it here: https://trac.wildfiregames.com/wiki/GameDataPaths)
