OK, fair enough. > I replied to your bug report about this. Again : nothing has changed with > regard to autoscrolling, this code hasn't been touched and is independant > of the canvas drawing code. It works fine here, anybody else sees > autoscrolling problems ? That's really interesting. Just to confirm that it's not merely a question that I need to go get some sleep, I dragged out 1.0 and inserted exactly the same giant audio segment into it. The difference between them is really huge. With 1.0 I can drag this segment 150 bars in a very reasonable time, and it's very smooth and fluid along the way. With CVS, it's unresponsive, jerky, and excruciatingly slow, taking probably at least 10 times longer to get there. I wish I had some way to show you a video of it. It's really horrible. > I did improve it in some specific circumstances, but that was quite a while > ago already.

The playback pointer is no longer making me nauseous, I'd agree. Everything overall is hugely less fluid than it used to be though. Dragging out a new segment is flickery. Moving or resizing a segment is flickery. Scrolling the canvas (scrollbars, not autoscrolling) is flickery. Flicker is, on balance, less important than other problems, but it makes post-1.0 have a significant (although I think, yes, less significant than it was) degree of looking like some kind of also-ran shareware instead of professional software. This is another thing where video would be so useful. You have to see what I'm talking about to appreciate it, and it sounds like you probably don't. Just for the sake of comparison, I have unacellerated (no DRI) i845g on-board video on a 19" LCD monitor on a 2 GHz P4.

You're definitely missing the bit that changes the wave form in response to the volume setting. I cranked it in 1.0 and saw the little squiggle get much taller. That never seems to happen in CVS, even after I take a lot of steps to try to convince it to update. Either it's not happening, or it's not updating. (Probably the former. Some tricks to force an update are pretty solid. Like saving the file and re-loading it.) Overall, though, this segment in question really does have a rather low level, and the out-of-the-box preview in 1.0 is quite possibly identical to CVS. They both look like a straight line perturbed by occasional little bumps, with all of the bumps curiously only coming above the line. In 1.0, though, I can get a little better sense of what's what by bumping the volume. > Oh, you meant previews color. Yes, I did. These are really the least of my > worries, to be honest :-).
