We've seen reports in various threads that some players mouse position is off by a given amount in windowed mode. Since we can't reproduce it here at the studio we need your help to get information on it. 1. Is it still happening? 2. Does it affect highlighting/interacting with objects in the game world? 3. Does it affect the User Interface? 4. What is your desktop resolution? 5. How large is the game window compared to your desktop? 6. Does the amount that its off by change based on window position 7. Does turning off the title bar fix it? (Show Frame option in Graphics tab) 8. Are you running any background applications that could be messing with your mouse position? (like Synergy, OS Emulation) 9. Are you using multiple monitors? Please only reply to this thread if you are affected by this bug.
