OK, I have discovered that the culprit is the Compiz fade animation on close for Tooltips.
========================= Workaround: ========================= In Compiz Settings Manager, under Animations, "Close Animation" tab, look for the window match line for Fade that reads: (type=Menu | PopupMenu | DropdownMenu | Combo | Dialog | ModalDialog | Normal) Edit that line and add to the end of it: & !(class=\.exe$) ========================= Resolution: ========================= Please add this rule by default so as to avoid bothering Wine users.

Same problem on both Oneiric and Precise (up-to-date). When a tooltip from a Wine app disappear, its shadow remains. This can quickly leads to an unusable window. To clean these shadows, I have to move the window. I confirmed this bug with Mathcad 14, GeNIe and some others not-known apps. It does not happen, for example, with VLC or Steam. If you want to test with something free and lightweight, you can try with Sumatra: http://blog.kowalczyk.info/software/sumatrapdf/download- free-pdf-viewer.html Attached is a picture of a rather extreme case (made with a non-free app).
