It's odd that playing music in Wine would trigger graphical problems. What are your system specs? Maybe your system just isn't up to the demands. Have you tried disabling desktop effects? I can't reproduce your problem. I downloaded foobar2000, and can play it and Flash videos in native Firefox with no problem. I can even play Flash videos in Firefox in Wine and in native Firefox at the same time. I notice you said you're using Wine 1.4; try upgrading to 1.5.5, as a lot of changes have been made since 1.4 that affect media playback. (1.5.5 is what I'm using.) If that doesn't fix it, post terminal output.
