Hello,
I have a Corsair K63 Wireless Keyboard and a Corsair Dark Core RGB Pro SE Gaming Mouse, both connected through their wireless dongles to my Xbox Series X and both working fine with other games.
I have this issue in DayZ where they both work for walking, looking, aiming & shooting, but the mouse does not work / the mouse cursor does not show up in the main menu nor in-game on the inventory screen when in wireless mode.
The cursor does show up and work when I connect the mouse via cable, but it would be great to be able to use the mouse wireless as with other games.
