of recalculating the positions of things in the bar, so, if anything
modern versions should be quicker.
Oh my god! Y-y-yes!  You betcha, it speeds things up (why haven't i
done
this sooner?)

The easy test for me is going back and forth between [Home] and [End]
positions.  Also, cursoring forward/back with "Ctrl+[Left/Right]"
With
the cursor animated ("highlighted"), I wait several seconds with
these
operations, with the staff scrolling sideways in front of me.  With
the
cursor highlighting turned off, the (non!)scrolling is instant! I
love
it! (it's truly a relief... apologies to the animators... it's a
clever
and beautiful idea but it's been slowing me down, at least on this
system — Intel(R) Core 2 Duo CPU T5800  @ 2.00GHz, Ubuntu Maverick)
Hmm, I wonder what can be going on here - I'll try to test out on a slow
windows box that I can get to later today. Otherwise I'll have to ask
you to point a camera at the screen and video it!
When you say several seconds, during those several seconds is the
transition effect taking place, e.g. the music sliding sideways, the
cursor rectangle growing smaller? Or is there some delay and then the
transition effect happens in about 0.2 seconds? Well, I'll see if I can
reproduce this for myself.

Yes, the transition effect is happening, when the feature is turned on — the measures scrolling left or right. And that's what seems to eat up the time, mostly, as well as the cursor rectangle growing smaller, just as you describe. But that's slow and choppy for me (or at least, slow compared to what I assume is the original target speed).

And, you're right — it would need to be a video recording completely external to the system; otherwise, the video capture software would probably affect the sluggishness (I guess I'll try both methods)
