might it be an issue of graphical drivers? I experienced that rendering everything on debian is so slow... just an example: i use mplayer from terminal to listen my music (if you have some more usable solution just let me know!) and rendering the numbers of percentage growing takes abot 50% of cpu... that's crazy! so i keep open another tab (of terminal) to switch there and let mplayer work calmly... I tried om2008.12 and animations are really fluid... nothing compared with previous om versions... might it be a kernel issue? something that we can copy on debian ;-) ? d
