NVIDIA's Wayland EGL implementation sets explicit-sync acquire and release points while presenting a frame. The requests emitted by eglSwapBuffers and its final surface commit must be treated as one logical transaction. The pointer-warp path can commit the main surface from the input thread while the render thread is inside eglSwapBuffers. If this occurs between the explicit-sync requests, the cursor commit applies incomplete pending state and the compositor disconnects the client with: explicit sync is used, but no release point is set Add a surface lock and hold it across EGL presentation. Use the same lock for direct commits, frame callback registration, and pointer-constraint updates, replacing the narrower confinement lock. This prevents another thread from splitting the EGL transaction and removes the need for __NV_DISABLE_EXPLICIT_SYNC=1.
