I recently migrated to ubuntu 8.10, from fedora 10 and opensuse 11.1 before that. Curiously, when in fullscreen mode wine draws applications to the upper left of the screen as opposed to center. Im sure there is a simple command line param to fix this, I don't see it in the wiki though...
To elaborate: Desktop = 1024x600 App = 800x600 When running App in fullscreen mode App is rendered in the upper left hand portion of my monitors full resolution as opposed to being centered in it. I have never had this issue with any other distribution, but as I said it seems there should be a parameter if not to center, to force x and y offsets
