With an icon pix with an alpha channel, we must set the icon bg to the ParentalRelative pixmap. Then when we draw we should first clear the icon bg, with the icon at the good screen position so that the icon bg is "root" transparent. Then we can draw the icon and the alpha channel is well composed with the root bg. The flickering you can see is caused by the icon bg clearing. The only way I see to remove this flickering at focus change, is to compare certain entries of the hi_cs and cs colorsets and to draw only if these entries are different *or* the icons has not been already drawn. This leads to add a new entries in the FvwmWindow struct: "an icon draw count". This is a bit complex for this flickering which is caused by an icon state change (so this is maybe a feature o:) ???? > Ok, one more bug for you.
