One long standing bug in Live 9, that I experienced again the other day and that I'm talking to Ableton support about after having supplied a status report to them, is the auto-scrolling mixer window that keep scrolling back to either side.
You can watch a video illustrating the symptoms of this auto-scrolling bug
Please assist in finding out how to reproduce the issue
Support are saying they are aware of the issue but that they can't recreate it their end. That may very well be the case cause I can't identify the steps to recreate it. I'm turning to our collective experience of this and am asking for your help in creating a test case Ableton can use to fix this issue. Please share your experiences and observations with this one.
Sometimes the mixer window has an irritating bug as illustrated in the video link above. The mixer window will scroll back to either side after you have commenced scrolling to the other direction.

Member Skimo sep 24 2014 in Horizontal Scrolling in session view, live 9 Bug??"I think I've managed to verify that this occurs when you drag a new device (be it a live device or a VST or even a sample/wav) across the arrangement view/session view.. Live kicks in its automated scrolling so that the user can scroll to the point where they want to drop it.. Only sometimes you're not aiming to drop it in the arrangement view or the session view (but instead in the device chain for example) - it carries on the trend because I think it somehow loses track of where the cursor was at the last point.
My workaround above works to resolve in each case that this happens (or has done for me anyway) and I think the scrollbar is the 'if object is past this point, stop scrolling' trigger, I reckon we're perhaps flicking the mouse over the scrollbar too quickly for it to realise that we've done so, thus spawning the auto scroll bug."
Bug solutions and workarounds:
It seems that in multiple cases you can fix the issue somewhat reliably without restarting by dragging another plug-in or built-in effect or device on top of the scrollbar. While still holding it on the scrollbar, cancel the action, by escape or just dragging it back.
