Same audio segment, no previews. Select, drag toward edge. It's moving at about one pixel at a time, with little spurts. The segment is flashing rapidly between its normal color and the selection color, and there are two distinct regions of color which are cycling in opposition to each other. Little green grid lines are flashing on and off as part of this cycle too. All this light show nonsense seems to be what's slowing everything down. Once I sit here long enough for it to wind up, it does eventually jump about one bar per jolt, in between conniption fits, but the fits eat up a lot of time, and the scrolling is very slow and jerky. OK, now a big MIDI segment (still no previews.) Same thing exactly, but with the added bonus that in this region there are neighboring segments with visible labels. The labels are flashing on and off, in opposition to one of the regions of the dragged segment. Left side goes dark, neighboring labels flash off. Left side goes light, neighboring labels flash on. This phenomenon right here is slowing everything down so badly that I never get into anything even vaguely resebling the fast-scroll mode. It's crawling along, flashing all this stuff somewhere around 5-10 times for every pixel that the canvas eventually scrolls. Turning the labels off helped quite a bit, but getting rid of the labels is a cop out. The underlying problem seems to be really inefficient drawing dragging everything down. I'm not sure if there's actually anything new about the "light show." It could simply be that the new drawing methods are the culprit, doing the same thing as always but dramatically more slowly. Now that I think about it, Mom's digital camera has a video mode. I could do some 10-second MPEGs if you want. There's no way you could see this and think everything is A-OK, so I presume it must look a lot better on your box. Especially since I know you don't drink booze. :) -- Michael McIntyre ---- Silvan <[EMAIL PROTECTED]> Linux fanatic, and certified Geek; registered Linux user #243621 http://www.geocities.com/Paris/Rue/5407/ http://rosegarden.sourceforge.net/tutorial/ ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
