Resizing the desktop window on the fly is not supported at the moment, it's not specific to systray. This is bug 13034.
The problem is unrelated to the actual resizing action. It doesn't matter if I have µTorrent/Wine running or not when resizing, once I try using it with dual monitors the systray icon breaks and I can't get it back unless I run with a single monitor. This of course includes tests with restarting the computer etc after switching resolutions, to make sure it's not the actual resizing breaking things.
Then it's a different problem. Please file a new bug for this.
