This is likely a rare edge case, but in music that has lots of invisible meter changes, when viewing signposts they usually stack vertically, but can still be interacted with as usual.
However, in the screenshot I’ve filtered an orchestral score to only show the oboes and cor anglais (CA not in the movement shown, so it’s just the two oboes). The resulting view truncates material above these instruments, effectively cutting off the view of the stacked meter signposts.
Is this expected behaviour? I would, I think, have expected to be able to see all signposts and interact with them.
