--- Comment #8 from Seppo Yli-Olli seppo.yli-olli@iki.fi 2008-12-12 05:11:25 --- I'd like to note that for me it's not just a swirly move that makes it disappear. It can be a slow one too but it has to happen near the workspace edge. The edge seems to suck Winamp straight out of the workspace making it invisible. Swirling fast in the middle of the screen seemed harmless to me if it stays clear of workspace edges. (So I don't think it's related to the fast moving at all, rather desktop environment workspace switching being attempted and being failed. Are Wine windows supposed to be capable of doing that?) It would also explain why they seem to be "outside the screen". Adjacent workspaces are technically outside the screen.
