Was definitelty happening in 6.0.2: https://www.steinberg.net/forum/viewtopic.php?f=19&t=10936
Odd how some of you don’t have this and some do. If you read the post above you will see that in my case it didn’t use to do it then all of a sudden - apart from a brief remission - it did. This was mid-project. Bizarre and really hard to understand.
I’m pretty sure it only started in 6.0.2, I noticed straight away as the particular project had loads of automation in it. A big nuisance - you don’t realise how much you’ve been relying on seeing them until they’re not there, for all the reasons stated here. I think the only thing I’d been fiddling about in was the Automation Panel, might have made a few selections via it but not to perform any edits, can’t really remember, but it might be a place to try and get it to repro.
[EDIT] Seems to be hiding the points all the time now, even on older projects I haven’t touched in ages. Can’t even get the repro in the above post to work, either, darn it.
It would be nice to know what the behaviour officially should be.
[EDIT 2] Thanks to this post further down for pointing out it’s behaving as per the 6.0.1 release notes (p.9): https://www.steinberg.net/forum/viewtopic.php?f=19&t=11328&p=74622#p74622
So all of you with always visible points can consider yourselves very lucky!
