--- Comment #7 from billstei billstei@hbci.com 2010-06-07 22:18:54 --- Some additional info/findings:
The StreamHijacker GUI/window is divided into several sections each with transparent areas between them, where graphics from other programs are 100% visible beneath (Vista). In Wine 1.2-rc2 these transparent areas are painted with what I referred to in Comment #6 as a pink color, with no transparency.
Another test, using Ubuntu Karmic and a different video card, an Intel 965GM, shows the pink flicker occurring but noticeably shorter (as opposed to Ubuntu Lucid with a GeForce 6150 video card in Comment #6).
Again I will gladly move this data to a new bug if that seems appropriate at some point in this investigation.
