--- Comment #6 from Jörg Höhle hoehle@users.sourceforge.net 2011-09-06 08:17:59 CDT --- Still present in wine-1.3.26 with Ubuntu Intrepid. Another strange effect: if I start metacity after xterm and wine, switching to wine's desktop window will not turn everything black. Instead the screen behaves like a monochrome one and some of winecfg's tab content is visible, as well as xterm's and xclock's content (all B&W despite ls' colourful listing).
Activating xterm's window and all colors look normal again, even Wine's about glass (except 8bpp is not enough to render all its red gradient).
