--- Comment #3 from Henri Verbeet hverbeet@gmail.com 2011-05-21 11:31:14 CDT --- "EQ overflowing" happens when the X server stops processing events, typically because a driver is e.g. stuck in a loop or waiting for the result of an ioctl. This is almost certainly a bug in fglrx. There's a very small chance it's in the X server itself, but I doubt it. It's not a Wine bug, by definition. Even if Wine does something wrong here, it's not allowed to lockup the X server.
