Hi Mutlu, Go ahead modifying compiz/libdecoration/decoration.c, I'd like to know about your results/experiments. As I said before, I successfully got the opaque-only title bars and opaque window decoration displayed but anything non-opaque won't work.
What I didn't get/understand at that time was the fact that compiz doing all the blending, effects and windows animation to a 16bit physical screen (and seems like the transparency was working) and at the same time, the window decorator failing to create 32bit offscreen pixmaps, and thus windows get displayed without any title bars or surrounding decoration, which is somehow contradictory. Let me know about your changes. Regards, Ilyes Gouta. On Tue, Jan 6, 2009 at 11:33 AM, Mutlu T. <[email protected]> wrote: > Hi there, > > Thanks a lot for your prompt response.
