I've been experiencing a few bugs with automation items but just got time enough to document them.
1) Rounding issues with automation items:
2) Can't draw or resize automation items when the grid is set to 1/32:
3) Logic when copying/pasting automation items isn't optimal:
In that GIF you can see I'm trying to paste those two items using the action "Paste items/tracks, creating pooled..." and I'm failing at each and every attempt unless I select each item individually or using lasso selection all over the items and not just the labels.
