Poor performance of track zoom

I have a demanding session with 1000 tracks in it. When using the vertical zoom in/out function, there is a 1 to 2 second delay before the UI updates. Holding vertical zoom out down will amplify this, causing the application to lock up for 15 seconds or more. Is there a way to improve this performance? The easy answer is “Don’t use so many tracks”, but I don’t like that answer. :laughing:
