here we go, this issue with OpenGL has finally pushed me to trash my
old Cinerama xorg.conf and go for the newest Xrandr which is just
awesome and i have OpenGL on both screens and the patch loads on my
external screen and it runs much more smoothly and nicely!! thumbs up
yet: the response from the MIDI input is not as fast as as i imagined:
what does it make it go so slow?
Rotating images shouldn t be such a big deal and since i plan to embed
this application on a small miniATX computer or similar i wonder what
can be done to address this timing issue..
