A bug fix has been merged into Wine that resolves camera jitter and glitchy mouse control in FPS games running on Linux under Wayland. The root cause was Wine's old cursor-warping method, which abused the zwp_locked_pointer_v1 lock/unlock cycle, causing warps outside the locked surface to be silently dropped. The fix switches to the newer wp_pointer_warp_v1 Wayland protocol (added June 2025), which provides direct cursor warping without pointer locking. The patch is already supported by KWin 6.4+, GNOME Mutter 49+, and wlroots 0.19+, and is expected to ship with Wine 11.9.
