It _seems_ OK to me. I haven't seen any problems yet that I can obviously
attribute to it.
However, there is some madness in autoscroll at the moment. Try recording a
MIDI track -- you don't even have to play any events into it to get a
recording segment, just so long as the transport is rolling in record mode --
and see what happens when the pointer reaches the end and autoscroll begins.
For me, it sparks a mad endless flap back and forward between two different
scrollbar positions (possibly the one where recording started, and the
current one).
If you can't reproduce this I can give more precise instructions, and/or try
it with that last patch reverted.
Also, here's a crash on changing the zoom level with some audio and MIDI
segments visible. I believe I had just moved the zoom slider twice in
succession to zoom in, and the first zoom appeared to work but the second one
crashed it. I suppose it's possible the repaint from the first zoom change
was still incomplete when I made the second change.
