Cursor in Dual Monitor runs out of game

Hi,

i installed cachyOS and now i have a problem:

If i play a game like Zero-K or 0.A.D the cursor is not fixed to the window or borderless or fullscreen, means im not able to scroll to the right side in game cause the mouse moves to the second display. if i change the resolution to 7680x2160 the game fullscreen (borderless) both monitors but im also unable to scroll thru the right side.

is there a solution?

Running CachyOS with KDE Plasma on Wayland with Nvidia 570
