We are currently using today's latest from github. But I remember seeing this problem before that.
I've searched for related problems on this forum and the issue tracker. Are there any known potential causes? Is anyone else out there having a similar problem?
I would love to be more specific...
Thanks
(Edit: Now that I know what's going on, I renamed the Subject from "sporadic/rare tick misalignment" to "alignTicks failure when zooming programmatically")
