Accessibility regression after 2026.62.30: Eye-tracker mouse move events stopped working
Eye-tracking software successfully moves the Windows cursor and clicking works, but Arena does not respond to the synthetic cursor movement. Hover states don't activate and cards cannot be dragged. Moving a physical mouse does generate the expected hover/drag behavior.
This worked correctly before the 2026.62.30 update and stopped working immediately after installing it. The same eye-tracker mouse movement continues to work normally elsewhere in Windows and in other applications.
Platform: Windows 11

Additional technical detail: I found that Arena immediately recognizes the cursor position if I inject a small relative mouse-move event:
win32api.mouse_event(win32con.MOUSEEVENTF_MOVE, 1, 1)
This reliably triggers the expected hover behavior
The eye tracker appears to move the Windows cursor without generating the type of relative mouse-move event Arena now expects. For example, behavior similar to SetCursorPos() would explain the symptoms, although I have not confirmed the actual implementation.
This may help narrow the regression to how mouse movement is handled after the Unity update.
