Both games are running in fullscreen mode with 1680x1050 (like my desktop). I have tested this now with Windows XP and Windows 7 but there is no difference. After this I have enabled the virtual desktop and the bug doesn't appear anymore. Are you maybe using a virtual desktop? If yes try to reproduce the bug without it.
No, I'm using the game in traditional full-screen mode. I am using an older Ubuntu release, however, so it may be related to that.
