--- Comment #8 from Andrew O. Shadoura (I DO NOT USE COMPIZ) bugzilla@tut.by 2008-05-22 08:14:36 --- I got this again with wine-1.0rc1 (binary build from winehq).
Don't know how to reproduce.
Currently I have 3 programs running: Miranda IM, VMLAB, and WINE winhelp with VMLAB.HLP.
And again shadow is draw above popup.
