Yes, xcompmgr is silly eye-candy ... but it used to work well alongside wmii 3.9b1, and no longer does in tip.
My day-to-day setup involves mostly Emacs and rxvt-unicode, and I tend to use playing video on the root window as a convenient way to keep noodling on work while I catch up on news or movies. Emacs and rxvt-unicode work great with composting window managers, which has been nice. At some point I decided to play with wmii tip, and it just refuses to play well next to xcompmgr (clients visually disappearing, and then reappearing on mouse over, for e.g.). Clearly this isn't a huge issue to everyone, but it would be great if the regression could be fixed. Much better to keep the composting crap in xcompmgr, than anywhere near wmii. __armando
