Are too many redraws of the clips >being done? although the canvas itself optimizes what gets drawn, we draw on every motion event. we do not use motion hinting, because it doesn't work very well for the "local display" case - things don't move the way a user would expect. if you read about motion hints, they are only supposed to be used when it doesn't matter that the window is not "keeping up" with the mouse, and here it definitely does matter. this means that every time your mouse generates an interrupt, there will be a redraw done of that part of the canvas where the regionview used to be, and now is. and yes, thats a lot of redrawing :) when snap is on, there is no motion until a snap point is reached, and the canvas and our code optimizes away the redraws until that time. --p ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ ardour-dev mailing list ardour-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ardour-dev
