Hello again :-) -- when I add a tempo point (via tap tempo, in this case), and then delete it, there are some graphical anomalies.
- the point takes a second to disappear (i'd expect it to be instant?)
- thereafter, when playing, there are some mis-drawings of gridlines
- upon pause the grid re-draws properly.
Seems like it's just a graphical thing, but thought i'd mention it.
